SearchStax interview questions

I had a first round interview with a recruiter. Recruiter mentioned my information would be presented to the hiring manager and they'd know more information in a week. I followed up with recruiter after a week, and they did not respond. Recruiters, if an expectation is set, please be professional and take the time to let candidates know an update on their application. Time and energy goes into interview preparation please offer the courtesy to let someone know if they won't be moving forward.

I applied online and was quickly contacted for a 30-min interview with the principal recruiter. The interview took place at the agreed date and I was told that my application would have been reviewed. However, I have never got any feedback or response after the interview. I emailed the recruiter 1 week and also 2 weeks after the interview. No response. No phone number available to call the recruiter directly. I directly called the company headquarters 1 month after the interview, asking for an update, and was told that the principal recruiter would have been notified of my call. Again, I've never got an update from their recruiter. Almost two months have passed.
