InMobi raises the bar when it comes to unprofessionalism.
I had a couple of rounds scheduled with InMobi. The interviews were going good and all the rounds ended on a positive note.
After the first few rounds went well, the HR inquired about my expected salary range. On hearing that, she tried to negotiate me down there itself(even before all my rounds were complete).
For my next round, I had a very rude interviewer who didn't accept any solution other than the ones he knew. For every solution I gave, his response was that he knew a much better solution. On asking what the solution was, he responded with "I cannot tell you everything. You can google it". On googling, I couldn't find a better approach, even on geeksforgeeks.org.
Either he was an exceptional topcoder, or he was just bluffing.
After this round, I had another round scheduled. No one called me during the scheduled time. I tried contacting the HR, but it seemed like she had blocked my number. My entire day got wasted because of this.
If you don't want to continue the interview process with the candidate, at least have the courtesy to inform the candidate. Don't waste their time.
