I have cleard 1 st round of interview, but in 2nd round the person named shantanu sinha, asked me all system design related questions which i believe i've answered correctly and he did not asked any deep PM rleated question, because he said he wanted to check tech understanding of a person. But post interview he gave a feedback that person don't know basic fundamentals of PM. Generally i appreciate detailed feedback of interview rounds, but this one surprised me i got stunned when recruiter mentioned that you dont have basic fundamentals about PM, i got stunned and now i undersrood how good and relevant WBD interview process. I am getting a feedback regarding my PM skills without been asked any deep questions questions regarding Program management.
