Interview Preparation Tips
Experience: This round was for basic elimination of people weak in their Java basics and of course, logic !
If the basics are sound and nothing is rote learned, it shouldn't be very difficult to crack through this.
Keeping your logic logical and honest (if you know what I mean) helped.
Tips: Keep your basics in place and logic intact.
It is important to know what you know rather than know what you don't know.
For logic building, keep solving any puzzles, aptitude questions that come to hand.
Best way to learn about a language is to code in it EXTENSIVELY !
Round: Technical Interview
Experience: Saying you're favorite subject/what you're good at means you have to be the best at it.
Once you have your strong areas firmly in place, it is important to make the interviewer elicit that you are really good in those areas.
It's always a trap, a fusillade of a chain of linked questions where one wrong move can fritter away the entire journey till now.
There's a lifeline though and that is to say 'I'm not sure of anything beyond this' (Use it well and not you need not shy away from saying those golden words !)
Tips: Find out what interests you the most and work hard on developing your aptitude in those areas, to be able to answer questions that will never be asked in a straightforward manner.
All other areas of expertise which the position requires should be covered up as much as possible.
Round: HR Interview
Experience: Most importantly, you need to be sure of what you have, what you want and what you think this position can give you .
Tips: Be clear in your thought process and confident in your approach.
General Tips: Work Smart not Hard and you will find a way which isn't as long as it seemed to be !
Skills: Java, Operating Systems, Networking, Data Structures, Algorithmic approach to problem solving, Aptitude
College Name: Pune Institute of Computer Technology
Motivation: Start-up with entire engineering team in India and catering mainly to the US market !
Entire design and execution decisions taken by individuals.
Enough motivation :)
