Recruiter calls gets all info about you except don't want to talk about salary. First round of interview with 2 software engineers all technical questions very easy. Then 2nd round with two more senior engineers with behaviour questions . In 2nd round they are interested in how the work is done in your company what's the process within the company instead of your actual experience and some senior members I could still see being rude with response to answers. After all this process recruiter emails back with 'oh I forgot what was your salary expectation ' . And after getting a response which is not too inflated based on current market no response. Such unprofessional experience with such a big name of the company is least expected . So please clarify with the recruiter about salary expectations as first question before letting them check you out .
