Interview Preparation Tips

Round: Resume Shortlist
Experience: On the basis of CV they shortlisted approx 30 candidates for SDE position.
Tips: Must verify your CV from your seniors/batchmates.
Include all the projects, intern work or hall activities or anything you have done on your own which is related to or interest of company. If you know any back-end/front-end (javascript, php, mysql etc) language do mention. I think the cv shortlist was completely based on previous work and technical skills related to Web Development/Design mentioned in the CV.

Round: Technical Interview
Experience: I had one interview for approx. an hour, it includes both Technical and HR round, well mostly technical. Interview starts with tell me something about yourself. Asked in detailed about algorithms/web based projects mentioned in CV, make sure that whatever you have written you have complete knowledge about it. Asked to code few basic algorithms questions. Do mention about small project if you have done related to web development.
If interviewer says if you want to ask any question, its always better to ask one or two question.
Tips: Prepare tell me something about yourself way before your placement starts, a month or so. Write it down on a piece of paper, keep it to less than 120 sec, 90-100 sec is good.
A basic format would be like, your introduction, schooling (doesn't matter but if you have something good to say about), give an overview of your project/work experience mentioned in your CV.
You should cover all the necessary and important parts written in your cv in this question. If something interest the interviewer your interview can start from those topic you mentioned.
Just make sure whatever you have written in your CV, you have full knowledge of it. Interviewer is going to take you from summary of the project to how you have actually coded some particular function or stored data.
Interviewer will give you enough time to think and give answer, so don't just be in hurry and say anything randomly.
While writing code keep telling what you are doing, just don't sit and code silently, interviewer might say and give hints if you are doing it wrong.
Ask question if you have any doubt, or to frame the question properly. Cause most of the time questions are of one line and you're suppose to assume a lot of things so its better to ask questions and get it clarified, it may happens that interviewer wants to ask something else and you are solving something else.
If you don't know something its better to say no.

General Tips: Interviewer wanna see how you think and if you can code or not, so take your time, think properly, keep telling what you are thinking, interviewer will probably gives hints/help you to solve the problem.
Skills: SQL, Algorithms, Data Strucutre, C++, PHP
College Name: IIT Kharagpur
Motivation: Interested in coding, love web development stuffs.
