Stored procedures.

Was Asked to explain sorting algorithm of my choice.
I chose merge sort and bubble sort.

And questions regarding various situations :
What I would do if I got a Tech Support / Testing Project?
If I was comfortable relocating?
If I had a problem with night shift?
What I would choose to work on Web based Applications or Windows based applications?
I replied as I have worked on web before and a lot of major businesses these days are websites so I would choose web.
He then said even If you get a chance to work on a big application like SAP etc. that can manage huge organisations like TCS.
I said in that case I would choose windows based.

Interview lasted for about 40-45 minutes.I had to wait 5-6 hours before the interview.
Interviewers were very friendly.
They did try to heckle me a number of times and specifically asked me random questions to check my presence of mind while I wad writing code on paper.

I would recommend if you are preparing for a CodeVita/Digital Interview cover the following topics:
DS Algos(PriorityQueue, HashMap, Queue, LL, Stacks, Sorting).
SQL

Resume Projects
I wrote Java in my resume and was expecting questions on Core Java but wasn’t asked, I would still recommend doing Multi-Threading, Exception handling, OOPS.
Puzzles(If you have time)

If you have prepared some topics specially be sure to mention them in your examples
Example : I had prepared OOPS very well but didn’t mention while writing Code, should have mentioned.

All the Best!!
