Interview Preparation Tips
Experience: Test was challenging. Depending on the profile 5 tests were conducted, pure HW, pure SW, pure DSP, HW+DSP and HW+SW. The tests were of varying durations. My choice was HW+SW which had 4 sections: digital, analog, software and aptitude. The first two sections were pretty challenging.
Tips: Analog: revise EMC - bode plots + RLC circuits + op amps
Digital: not too much revision required. Questions based on analog were asked here too, so ref. above
Software: understanding of low level C concepts like stacks, function pointers, threads etc. were asked. Some questions on calculating time and space complexity of an algorithm. Mostly theory based MCQs
Duration: 165 minutes
Round: Technical Interview
Experience: Pretty straightforward interview with questions not limited to analog as the field of interest (it was the profile I was selected for).
Tips: Keep cool and work through the process in steps. For some of the tougher questions, the interviewer is helpful enough to suggest steps for proceeding forwards so it only becomes a question of voicing whatever approach you have towards solving the question
Round: HR Interview
Experience: Most generic HR interview ever. It was more casual that if I had been talking with friends.
Tips: General tips:
Be positive
Be clear and concise
Leave little hints in your answers that you are looking to work at TI after graduation (they value this a lot)
General Tips: Be open and calm. It's OKAY to crack a joke or two during the interview to lighten the mood, but sometimes it can explode in your face, so know your limits.
Skills: Software Skills, Analog And Digital Knowledge, Puzzle Solving Capability
Duration: 2
College Name: IIT Madras
Motivation: It is Texas Instruments. That is a good enough reason.
Funny Moments: Nothing to say here really. Probably getting selected was the funniest thing all day

- Q2. Find the voltage through the resistor
- Ans.
To find the voltage through a resistor, use Ohm's Law: V = I * R
Use Ohm's Law: V = I * R, where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor
If the current flowing through the resistor is 2A and the resistance is 5 ohms, the voltage would be V = 2 * 5 = 10V
Make sure to use the correct units for current (Amps) and resistance (Ohms) to get the voltage in Volts
- Q3. The interviewer just kept on adding an extra resistor in parallel and in series to the resistor and asked me to find the voltage
- Q4. He then asked a question on transient analysis ie 2 capacitors connected in series with a switch which closes at t>0 with the voltage across the 2 capacitors being 3 v and asked to find the total voltge
- Q5. Explain the working of a capacitor and resistor and relation between resistance and length , area
- Ans.
Capacitors store electrical energy while resistors limit the flow of current. Resistance is directly proportional to length and inversely proportional to area.
Capacitors store electrical energy by creating an electric field between two conductive plates separated by an insulating material
Resistors limit the flow of current in a circuit by dissipating energy in the form of heat
The resistance of a resistor is directly pr...
