Coviam Senior Software Engineer interview questions

There were 4 rounds 1. Online Screening test : Really easy. MCQs and 3 small coding questions. 2. F2F - Problem solving : Tower of Hanoi, Altered Merge Sort Solution and Fibonacci Series (Really !!!); Pretty easy 3. F2F - Java Round : The interviewer was very experienced and knowledgeable. Questions were mainly about Garbage Collection. How Stack and Heap variables are cleared of the memory; Different garbage collection algorithms. Class Loaders etc. Good and Hard. 4. Puzzles and basic programming. Direct interaction with the CEO where he explains about the strategies and growth of the Coviam. He was really cool and he knew what he doing precisely with company moving forward. HR Round - Which I think is a complete waste of time. I was not impressed with the handling the negotiation of the offer. Fortunately or Unfortunatley(:P) I didn't accept the offer.
