They called for an interview on May 5th, 2016. They conducted almost four rounds of discussions:

3 Technical 1 Managerial

Then, HR asked me to fill up a form and gave brief details about the pay structure, etc. The next day, they called to inform me that I had to take one more onsite technical discussion.

Till date, they haven't come back. It's neither a rejection nor in progress. Two months of waiting without feedback.

Now, I feel I wasted my leave to attend this interview and wasted one full day.

Design patterns, SOLID principles, IEnumerable, IQueryable, multithreading, WPF custom controls, OOPs concepts are a little tricky, garbage collections, weak references in C#.
