Initially got a call from the recruiter and they shared an hackathon coding link which was basically mysql based questions. Once the coding exam was cleared I had my first round of interview based on basic sql questions.After clearing the 1st round there was 2nd round which I cleared as i got good response from the interviewer.But after that i did not get a call back from recruiter .after sending several follow up mail I got a reply stating that my profile is on-hold status. This was disappointing to me because i was expecting a postive response.So my effort of giving 3 interviews only made me realise that we should never get our hopes up if we get a positive response from the interviewr.
