There was one telephonic round which lasted for 25 minutes. Started with usual introduction and was asked few technical questions. I was called for a 1:1 after 4 days. It consisted of 2 technical rounds and one managerial round. I was asked to write programs during the technical rounds which tested the fundamentals of pointers. In the initial 10 minutes itself I was sure that I am not doing satisfactorily because it involved writing the actual code and not just outlining the logic was sufficient. The interviewers wanted the fully working code to be written.
