Prime Focus Technologies Senior Software Engineer NET interview questions

Two rounds of technical.First round was taken by Senior Head of company for checking your database skills.especially DB design. Second round technical guy was bit arrogant and was trying to demoralize me by any answer I gave.then he asked three logical questions saying less memory consumption and fast data retrieval should be be considered while writing your logic.first question was basic Star pattern, second was check palindrome, third was fetch me an prime number based on the index given by user from dynamically generated list of prime numbers. He told memory and fast data retrieval just to confuse me. I completed all three programs and later on he asked two puzzles two bucket puzzles and monkey climbing pole puzzle.overally easy interview process.he did not even asked any oops or MVC. nothing. went inside 10 am and came out by 2 pm.
