Interview Preparation Tips

Interview preparation tips for other job seekers - I was interviewed for the position of Principal Engineer. Had 2 rounds of technical and in depth discussions on topics. After 2 rounds running close to 3 weeks time, they mention your profile is not suitable which could have been done during resume screening itself. Even after seeing the reviews here about long interview process and no proper interview standards and feedback, I took a chance and my time was wasted in their interview process itself without respecting my time and efforts. And regarding the interview I am quite sure of my performance being an experineced person in the industry.

Interview Preparation Tips

Round: Test
Experience: Only a few students will get shortlisted who do all the questions correctly.

Round: Other Interview
Experience: First 4 rounds on day 1 and this are just to shortlist for more rounds on some other day.
Tips: They will focus on almost all the concepts of computer science.You need to practice a lot and start it right now. Should be easy if you have prepared well enough. Use your holidays to start preparing for placements.

General Tips: Sooner you start, better your placement will be as lack of practice & last day study works only for exams but never for interviews. You'll get enough time to prepare for interviews once you get shortlisted. Focus on it even if you are placed already.
Skill Tips: They will focus on almost all the concepts of computer science.

Interview Preparation Tips

Round: Technical Interview
Experience: On-site interview (5 hours).

4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.

The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.

The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.

The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.

The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.

Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

Round: Test
Duration: 1 hour

Skills: General Coding And Problem Solving, Puzzle Solving Capability
College Name: NIT Jamshedpur

Interview Preparation Tips

Round: Test
Experience: The first consisted of an online test which had an aptitude section which was pretty simply and then a programming section consisting of three different programs. The programs were logical required basic knowledge of array, sorting and a little bit of data structures.

Round: Technical Interview
Experience: Around 13 of us were shortlisted for the interview round, B.Tech and M.Tech included. The interview round was mostly interactive, where we had to mention about the various interns that we went through. A few programming questions were asked based on topics which we were comfortable with.
Tips: Just get used to coding, data structures and basic aptitude. GRE preparation as such helped me.

Round: HR Interview
Experience: Finally there was a HR round in which I was asked as to why I would like to work in Samsung R&D and general things about interests and future plans. On the whole Samsung took 3 B.Tech students and 2 M.Tech students when they came for placements apart from PPOs.

General Tips: Personally I feel that one should apply in only those companies in which they are sure of having job satisfaction. So don't apply to companies which you are not interested in just for the sake of having a backup because once you are placed you do not have a second chance.
Do not get dejected if you do not get through in the first few tries. Keep your hopes up and be confident when ever you get to interview rounds. Try to be assertive when giving answers. It is some times exhausting to go through placements but the moment you get placed you will have the best feeling ever.
Skill Tips: Just chill and take the test. Once you clear the online test, irrespective of your pointer if you have a good profile you can convince the interviewers.
