eBay Software Developer interview questions

In the phone screen I was given a hacker rank type of problem, you know the ones with a long statement and nothing challenging to do but just get some job done. I wrote the working code and covered all the edge cases elegantly and in detail but the interviewer complained that there were too many if-else in my code. I said that in nervous I was just trying to cover all edge cases, of course I can optimise it a bit more to make it more cleaner but then I got a reject on the same day. Do not know what they want. I mean I think it is unreal to expect a complete production quality code in stressful environment of an interview.
