Brocade is a company that solely works on C (not even C++). Therefore, whatsoever a great knowledge you have about object oriented features or JAVA, they wont going to ask you any Question in these fields, unlike most other companies.
My technical interview lasted for 1 hour, followed by HR interview of 1.5 hrs duration. I was selected.
Technical Interview: They asked question related to String handling, Trees, Linked List -- a lot of data structure. Brocade is a networking company, so brush up ur networking knowledge before appearing for a interview. They will gonna drill down into TCP, OSI layer stack , UDP, Routing protocols and so on. They asked me the scenarios where u will prefer to use UDP instead of TCP and vice versa. I was Mtech, so be very much aware of your MTP thesis, they will ask you a lot of your MTP thesis, challenges u faced, how frequently u approach ur guide, how u negotiate a problem with guide etc etc. These were all was a part of HR interview.
