Written Test
Section titled “Written Test”A shared aptitude section (quant, logical reasoning) plus a section specific to your applied profile - analog electronics for Analog Design/Layout roles, digital logic and computer architecture for Digital/Embedded/Software roles. Some drives run this on HirePro; software-leaning profiles sometimes get a small MCQ-only technical section instead of a coding round.
Common questions
- Quantitative and logical reasoning at a standard placement-test difficulty
- Analog section: RC/RLC circuit behaviour, op-amp basics, network theorems
- Digital section: number systems, logic gates, basic computer organization
Full round-by-round breakdowns are on the Texas Instruments interview experience page.
Technical interviews: analog roles
Section titled “Technical interviews: analog roles”For Analog Design and Analog Layout profiles, expect 1-2 rounds built around circuit intuition rather than memorised formulas. Interviewers commonly spend the first 20-30 minutes on your resume and projects before shifting into fundamentals, then go deep on whatever project you mention involves a real circuit.
Common questions
- First-order and second-order RC circuit response, explained by intuition rather than differential equations
- Poles, zeros, and current mirrors
- SAR ADC sampling capacitance and Flash ADC gray encoding
- Op-amp, MOSFET, BJT, and CMOS basics
- Deep-dive questions on any ADC, LDO, or converter project on your resume (power, comparator topology, redundancy)
Technical interviews: digital, embedded, and software roles
Section titled “Technical interviews: digital, embedded, and software roles”Digital Design, Firmware/Embedded Software, and general Software profiles get a different technical mix: embedded C, RTOS concepts, and computer-architecture fundamentals rather than analog circuit theory. Some panels open with 15-20 technical questions before ever opening your resume; others go project-first.
Common questions
- Endianness, pointer arithmetic, and memory alignment in C
- Cache coherence, SRAM vs DRAM, virtual memory basics
- RTOS concepts: task scheduling, priority inversion, semaphores/mutexes
- FSM design, timing, and basic Verilog (Digital Design profile)
- Bit-manipulation and OS fundamentals questions
Project presentation (experienced and specialised roles)
Section titled “Project presentation (experienced and specialised roles)”Some experienced-hire and specialised technical loops add a short prepared presentation - typically 15-20 minutes - where you walk a panel through a past project and then field follow-up questions on the choices you made, trade-offs you weighed, and results you achieved. This is reported less often in mass fresher/campus drives, where the same ground is usually covered conversationally inside the regular technical interview instead of a dedicated slot.
Common questions
- Why did you choose this approach over the alternatives you considered?
- What would you change if you rebuilt this project today?
- What data or measurements backed this design decision?
HR interview
Section titled “HR interview”A closing 20-30 minute round on motivation, TI’s business, and practical fit (location, notice period). Several candidate reports note that reaching this stage usually means the technical bar is largely cleared already.
Common questions
- Tell me about yourself?
- Why Texas Instruments?
- TI makes analog and embedded chips used across industries - what do you know about our product lines and where you’d fit?
- Walk me through a circuit or firmware project from your resume in detail?
- Are you willing to relocate to Bangalore or another TI hub?
Sample answer frameworks for each of these are on the Texas Instruments HR interview questions page.
Analog depth is the real differentiator
Section titled “Analog depth is the real differentiator”Unlike most software-company loops on this site, a large share of TI’s India engineering hiring is genuinely analog and mixed-signal - not embedded-adjacent software with a hardware label. If you’re targeting an Analog Design or Analog Layout role, DSA-style prep will not help much; the bar is circuit intuition (can you reason about a Bode plot or a current mirror out loud, not just recite the formula) plus the ability to defend a real analog project in detail. If you’re targeting Firmware/Embedded Software, the bar shifts to C fundamentals, RTOS, and computer architecture rather than analog theory - so confirm which track you’re interviewing for before you prepare.
Common technical interview questions and answers
Section titled “Common technical interview questions and answers”Q: Explain the step response of a first-order RC circuit by intuition rather than by solving the differential equation.
At the instant a step is applied, the capacitor voltage cannot change instantaneously, so it still holds its previous value and the full step appears across the resistor, giving the maximum initial current of the step amplitude divided by R. As charge accumulates, the capacitor voltage rises, the voltage across the resistor shrinks, and the current falls proportionally - so the rate of change is always proportional to how far you still have to go, which is what produces an exponential. The time constant is R times C: after one tau you have covered 63 percent of the gap, after three tau 95 percent, and after five tau you are within a percent. In the frequency domain the same circuit is a single-pole low-pass filter with a minus 3 dB corner at 1 divided by 2 pi RC, rolling off at 20 dB per decade with 45 degrees of phase lag at the corner.
Q: What is a current mirror and what limits its accuracy?
A basic current mirror is two matched transistors sharing a gate or base node, with the reference device diode-connected so its gate-source voltage is set by the reference current; the output device, seeing the same gate-source voltage, sources a proportional current set by the width ratio. Accuracy is limited first by channel-length modulation, since the output current depends on the output drain voltage through the finite output resistance, and second by random mismatch in threshold voltage and mobility, which improves as the square root of device area. A cascode mirror shields the input device from output voltage swing and raises output impedance by roughly the cascode transistor’s intrinsic gain, at the cost of headroom; a Wilson mirror uses feedback for similar benefit. For BJT mirrors there is an additional base-current error of about 2 divided by beta, which a helper transistor removes.
Q: How does a SAR ADC work, and how does it compare with a Flash ADC?
A successive-approximation ADC samples the input onto a capacitor array, then performs a binary search: the DAC is set to mid-scale, a comparator decides whether the input is above or below, that bit is latched, and the process repeats for each lower-weight bit - so an N-bit conversion takes roughly N comparator decisions and one clock each. That makes it moderate speed with excellent power efficiency and only one comparator, which is why it dominates 8 to 18 bit general-purpose converters. A Flash ADC instead uses 2 to the power N minus 1 comparators against a resistor ladder to resolve the whole code in a single clock, giving gigasample speeds but power and area that double with every added bit, which caps it near 6 to 8 bits. Pipeline converters sit between the two, and sampling capacitance in a SAR is set by kT/C noise and required settling, trading noise against input drive requirements.
Q: What is the difference between SRAM and DRAM?
An SRAM cell is a six-transistor cross-coupled latch that holds its value as long as power is applied, so it needs no refresh, has access times in the low nanoseconds, and is used for caches and register files - at the cost of large area and higher static leakage. A DRAM cell is one transistor plus one capacitor, so it is far denser and cheaper per bit, but the charge leaks away and must be refreshed every few tens of milliseconds, and reading is destructive so the sense amplifier writes the value back. DRAM access is also slower and has row-activate, column-access, and precharge timing constraints, which is why memory controllers reorder requests to exploit open rows. That density-versus-speed split is exactly why systems use an SRAM cache hierarchy in front of DRAM main memory.
Q: What is endianness, and how would you detect it in C?
Endianness is the byte order used to store a multi-byte scalar in memory. Little-endian machines, such as x86 and most ARM configurations, place the least significant byte at the lowest address; big-endian machines, common in network protocols, place the most significant byte first. Detect it by writing a known value and reading it back through a narrower type: set uint32_t x equal to 1, then take unsigned char p equal to the address of x cast to unsigned char pointer - if p[0] is 1 the machine is little-endian. It matters whenever bytes cross a boundary, which is why network code converts with htonl and ntohl, and why casting a byte buffer straight to a struct pointer is unportable and can also violate alignment requirements.
Q: What is priority inversion and how does an RTOS solve it?
Priority inversion happens when a high-priority task blocks on a mutex held by a low-priority task, and a medium-priority task that needs no such lock preempts the low-priority holder - so the high-priority task waits indefinitely on a task it outranks. The Mars Pathfinder resets in 1997 are the canonical field example. Priority inheritance fixes it by temporarily raising the lock holder’s priority to that of the highest waiter, so the holder cannot be preempted by a medium-priority task and releases the lock promptly. Priority ceiling protocol goes further by giving every mutex a static ceiling priority assigned on acquisition, which additionally prevents deadlock and bounds blocking to a single critical section - most commercial RTOS kernels offer inheritance as a per-mutex option.
Q: What is the difference between a semaphore and a mutex?
A mutex enforces mutual exclusion and has ownership - only the task that took it may release it - which is what lets the kernel implement priority inheritance and detect recursive misuse. A semaphore is a counting signal with no owner: any task may give it, so it is the right primitive for signalling between an ISR and a task, or for limiting concurrent access to a pool of N identical resources. Using a binary semaphore where a mutex belongs is a classic embedded bug, because it silently discards priority inheritance and permits one task to release a lock another task holds. Also remember that a task must never block on a mutex inside an interrupt service routine - you signal a semaphore from the ISR and do the work in a task instead.
Q: Count the number of set bits in an integer efficiently.
The naive loop shifts right and tests the low bit 32 times regardless of the value. Brian Kernighan’s method is better: repeatedly do n equal to n AND (n minus 1), which clears the lowest set bit each iteration, so it loops only as many times as there are set bits. A lookup table over bytes gives a fixed four table reads for a 32-bit word, and most modern instruction sets have a single popcount instruction that compilers emit for the intrinsic. Watch two portability traps: right-shifting a signed negative integer is implementation-defined and can shift in ones forever, so use an unsigned type, and shifting by the full width of the type is undefined behaviour.
Frequently asked questions about Texas Instruments interviews
Section titled “Frequently asked questions about Texas Instruments interviews”What is the Texas Instruments interview process for freshers?
TI India campus hiring (mostly out of the Bangalore Design Centre) runs 3 stages: a Written Test (aptitude plus a profile-specific analog or digital electronics section), 1-3 Technical Interviews (roughly an hour each, usually starting with CV/project discussion before moving into circuit theory, embedded C, or RTOS questions depending on the role), and a final HR Interview. Some analog and hardware roles add a short project-presentation component where you defend design choices to a panel.
What questions are asked in Texas Instruments interviews?
Questions split hard by role. Analog Design/Layout candidates get op-amps, MOSFETs, current mirrors, RC/RLC transient behaviour, ADC architectures (SAR, Flash), and network theorems. Digital/Embedded and Firmware/Software candidates get embedded C (pointers, memory alignment, endianness), RTOS concepts, cache/SRAM-DRAM basics, and CPU/SoC architecture. Every technical round typically opens with 20-40 minutes on your resume and projects before shifting to core concepts.
How many rounds are there in the Texas Instruments interview?
Typically 3-4 touchpoints: a Written Test, one to three Technical Interviews (often over Webex, with screen share), and a final HR Interview. The exact number of technical rounds depends on role, campus, and whether you’re hired as an intern or full-time engineer.
Does Texas Instruments hire for analog design or software engineering in India?
Both, and the split matters more at TI than at most software-first companies. TI is fundamentally an analog and embedded semiconductor company, so its India roles include Analog Design/Layout Engineer, Digital Design Engineer, Firmware/Embedded Software Engineer, Applications Engineer, and Test Engineer - alongside a smaller number of pure software roles (tools, infrastructure, data). Check the exact job description before assuming your prep should be DSA-heavy.
How should I prepare for Texas Instruments interviews?
Match your prep to the role: revise core circuit theory (RC/RLC, network theorems, op-amps, ADC basics) for analog roles, or embedded C, RTOS, and computer-architecture basics (cache, memory alignment, endianness) for embedded/firmware roles. For every role, be ready to explain any project on your resume in real depth - TI panels probe projects harder than most fresher interviews, sometimes for 30-40 minutes on a single project.
Is there a project presentation round at Texas Instruments?
For some experienced-hire and specialised roles, yes - candidates report preparing a short (15-20 minute) technical presentation on a past project, then defending design choices, trade-offs, and results in front of a panel. This is less common in mass fresher/campus drives, where project discussion is folded into the regular technical interview instead of a separate presentation slot.
What is the reported salary for Texas Instruments freshers in India?
Community-reported figures (AmbitionBox, Glassdoor, 6figr) put fresher CTC roughly in the ₹14-25 LPA range depending on role and campus tier, with embedded/firmware and analog roles often at the higher end. These are self-reported aggregator numbers, not official TI figures - always confirm against your actual offer letter.
