Can speak English, can’t deliver in interviews
I feel like I can't speak fluently during interviews.

Interview Preparation Tips

Round: PRE PLACEMENT OFFER
Experience: Interns (both CS and IT) were selected in my third year. Pre-placement offers were rolled out to 16 of us which was roughly a conversion ratio of 1:3. A couple of ECE hires were added when SRI-B visited campus later.

General Tips: If you're in CS or IT, this is the only format your resume should be in: -----
Take your internship seriously. Have fun and all but also get your project done. It's not the end of the world if you don't get a PPO. Campus placements are tension-filled, no doubt, but a lot of people get equally good if not better jobs after missing out on PPOs.
Make sure you talk to your manager about the PPO process. She will be the one giving you your final review. So ensure that she knows you want the job. Prepare a fancy presentation for the HR. By fancy, I mean slick and professional. Think Apple, not flashy Microsofty graphics and stupid word art.
Skill Tips: Google GSAT (Global Samsung Aptitude Test) a week before the test and make sure you practice some similar CAT type questions. Questions are of medium difficulty and time management is a real issue (most of us were unable to finish properly). - I didn't have to use these but I've heard good things about codechef/topCoder and books such as Cracking the Coding Interview by Gayle Laakmann McDowell.

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.
