Vivo Software Developer Interview Questions and Answers

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.
