Interview Preparation Tips

Round: Resume Shortlist
Experience: No CPI cut off and It was open for all departments.

Round: Test
Experience: In muliple choice question Mostly questions were base on maths, probability, c programs, algorithms, Systems. If you are prepared then Questions were not that much tough. Keep strong concepts of Operating systems. For subjective part, Some problems were from maths proofs, some were from probability, some were from algo. We had to write algorithms. etc
Duration: 180 minutes

Round: Problem Statement
Experience: Questions were doable.

Round: Interview
Experience: Everyone was cool, They made me feel comfortable and then started asking questions.
Tips: If you have good rank in online coding competition, do mention it in CV.Most of the students think that GS asks only probability-puzzles. They did not asked me any question on probability or puzzle. Everything they asked was based on Algorithms problems and Operating system. I think it depends on team for which they are hiring. Most important point is don’t lose hope because you have low CPI or you are not good at something. Keep Operating systems fundamental concepts strong.

General Tips: We should balance in Placement and Compititive online coding. Keep in mind Placements and Compititive online coding are some what different things. Keep on improving our mistakes on daily basis. I would strongly suggest you to do introspection daily it will help you to find out your weaknesses and strong points, where we are going wrong etc. There are two thing on which we shoud focus.1. Preparation (I have told everything requered for preparation).2. Get output of all hard work. How to keep our mind on 100% output while the actual exam(placement).For this, I used to go for physical exercise daily in the morning and medidate for 20-30 minutes. Along with exercise i used to do Sudarshan Kriya(Art of Living). Meditation has lot of power :).
Skill Tips: Keep your OS fundamentals strong. To improve codgin skills practice as many problems as you can. Regularly participate in online coding competitions it really helps to solve or approach any new problem. Many time instead of correct answer the approach to solve the problems is very important. How you think, How you approach the problem is checked in interview.
Skills: Coding Skills, Operating Systems , Problem solving skills
College Name: IIT Guwahati
Motivation: The name GS itself enogh for motivation.
