I went through 5 rounds of interview and after HM round I came to know I have got negative feedback. My skill set were not up-to mark. After wasting more than 5 hours of a candidate you come up with single line feedback. Interview process Had Initial round with Hiring Manager (exploratory call) Two technical rounds : The panels were nice and humble. Fitment round Hiring Manager round: Somehow I realized that hiring manager joined the call with bad mood. Asked to write a code to print sentence from a file with some matching condition. I wrote and then she asked me to optimize it (in terms of space). I was unable. Write test cases around it I told around 10-15 she said ok and that's all. No further conversation.
