   Online test

   Online assessment: aptitude, core CS MCQs, two coding questions
   90 min35 questions+1 correct, -0.25 wrong (MCQs, one account)easy

   Section	Qs	Min	Topics
   Aptitude	12	20	time and work, linear equations, pie charts, averages, series, AP/GP
   Core CS / technical MCQ	-	30	OS, DBMS normalisation, trees, BST, computer organisation, HTML/CSS, Linux/Bash
   DSA	2	40	sieve and digit matching, string character mapping

   aptitude · OS · DBMS · web basics · primes · string transformation

   Platform differs (TI-run platform vs HirePro; one account cannot recall); duration 1.5 h by two accounts and 2 h by one. Sections timed and one-way. Boilerplate in C++ read only one word of input and had to be replaced by a full-line read.

2. 2

   Technical interview

   Single technical interview
   Webex / coding pair editor60 min

   projects · React hooks · OOP in C++ · virtual functions · min heap implementation · mirror tree check · zigzag tree traversal · ML metrics · SQL joins · rectangle overlap

   One round, 1 h. Candidate questions followed the resume: web stack, databases, ML (YOLO metrics), OOP. No HR round.

Advice from candidates

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

• TI shares a document of preparation material that mentions all the topics that are important. That material gives you a very good idea regarding what type of questions can be expected in the test and the interview. Study those topics, and that will be more than enough for acing the interview. They don't expect high-level complex concepts from you. They expect your fundamental concepts to be crystal clear. Some important topics from which questions are frequently asked are: Pipelining and hazards, FIFOs, buffers, memory organisation, Timing analysis, setup hold time, metastability, Karnaugh maps, digital circuits like counters, and reducing circuits.

• If online interview, use an iPad; it will be convenient for both you and your interviewer.

• Aptitude round is very easy and you will be able to solve everything with basic presence of mind. Still, for some practice of aptitude questions, you can refer the website "Indiabix".
