   45 min

   Section	Qs	Min	Topics
   MCQ	10	-	pointers, 2's complement, ADC/DAC
   Coding (C only)	3	-	bit manipulation, arrays, loops

   pointers in C · bit manipulation · digital electronics · MOSFET · probability · basic mechanical physics

   Duration 45 min in two accounts, 1 hour in the embedded software account. Sections can be started in any order but not toggled. Content varied by track: one account saw mechanical-flavoured basic physics plus MOSFET and probability questions, another saw C MCQs and coding. No negative marking per the embedded account.

   resume projects · block diagrams of projects · communication protocols · KCL and KVL circuits · filter design · op-amps · diodes · DC-DC converters · RF frequency bands · review of own test code · bit reversal

   One-on-one, friendly. About 1 h in one account and about 50 min in another; duration left null. One account got 20-25 electrical problems discussed aloud and 30 minutes of resume grilling. Interviewer guided when asked.

Advice from candidates

31 pieces of advice, in their own words. Names removed.

• Be calm during the interview and solve the problems with a fresh mind. Get proper sleep before the interview and check CDS mail regularly for any communications regarding to the placements.

  general · 2023

• Interviewer will generally help you guide in the direction to solve the question. Making some mistakes is fine if you have the grasp on the concept. To be honest, you can prepare for one of the topics I mentioned earlier but none of the questions might be from that topic. Since the syllabus is so vast, I think preparing for your weak points will be crucial. Brush up some coding concepts but don't spend too much time on it

  interview · 2023

• It was a bit lengthy, so the best strategy was to first solve the problems that you know and then go to the problems that takes more time.

  test · 2023

• The test was very lengthy, about 1 min per question. If you can't think of the method at first glance, it is best to move on.
