Pulse Secure Senior Software Developer interview questions

I was directly called in their office for discussion. First round consisted of a hand written test consisting of 5 programs to be completed in 1 hour, followed by two technical rounds. I was able to solve all the programs. But after two rounds, they came with feedback that programming is very good but networking knowledge they are expecting more. I previously worked in transport and application layer. But they expected L2/L3 practical knowledge. It was quite a surprise on the rejection since I was confident after giving those two technical rounds.

I got a call from respective HR and it was supposed to be a 1 day event preferably on a weekday and they scheduled it as per my convenience itself. Overall interview process will be 1 written coding round, followed by 3-4 technical rounds and a HR round. They asked all basic and standard data structure questions itself, mainly on linked lists, trees and maps. They will give you ample of time to solve the problems. They look mainly for quality of code. I could not clear as I was not well prepared most of the question I couldn't get to a logical conclusion. At the end even the HR gave me this feedback. With proper preparation for 1 month or so, this is crack able.
