Nakisa interview questions

Met the HR head at an on-campus recruitment fair. Submitted resume and cover letter via email. Got called for an interview. Interviewed with the HR head for about 30 mins, talked about previous job experience and some behavioural questions including salary requirements. This was tricky as she really wanted me to spit out numbers first and I wasn't able to weasel my way out of it. Then the head of Software R&D came in and I talked about my Master's thesis and he gave me two technical questions * Write and algorithm to find the 5th element from the end traversing the list only once * Design a database schema for a library system with different types of media This was my first technical interview and I messed up at a couple of places * What do you know about Nakisa? (I had no clue, I spit out whatever I'd seen on the website. Make sure you research the company and the position) * The first tech. question... it is pretty standard but I couldn't figure out how to do it. Easiest is to use a data structure like a stack or maintain 2 pointers. I got a really negative vibe from the tech guy. He seemed a little cocky and wouldn't help me out on the drawing board, just sat there staring at me. Also, they said .Net & Java but the first thing he asked me was if I was interested in flex programming.
