Candidate-reported interview process

The entire process took place in one day and consisted of 4 rounds in total, including Aptitude and a Technical round (coding - simple), another Tech round, and an HR round. The filtering is tough. The questions test your basic tech skills and maths. The coding round is on strings. The tech round is easy. They mostly ask questions about projects. All the best!

I am a student from VIT University, Vellore. The first round was an online test with four sections: aptitude, verbal, logical, and technical. The technical section was a bit tough. The second round was an online coding round where I was given two questions. The questions were average. I am from ECE and I did one question (the second one). Most of my friends solved the first question and got the output, but they were not shortlisted. They shortlisted me for the next round. The third round was a technical round, mostly on the projects in the resume. They asked me for every single detail about my projects, so you should be very clear with your projects.

I'm from ECE, but for this role, 3 branches were eligible: ECE, CSE, and IT. We went through a 4-round selection process. The first was a 2-hour online technical test with Quant's, logical reasoning, and ECE technical sections. Candidates who passed that had a coding round on the same day. We could choose between Java and C++ only, and had to program 2 codes for the given test cases, using AMCAT AUTOMATA online. Those who passed that had 2 more rounds: a technical interview and an HR interview. Both were elimination rounds. The difficulty was moderate for all rounds, totally doable!
