It happened with a company that makes the audio Codecs for Apple (you guessed it right).
It was supposed to be the most pleasant interview ever but not exactly. Here's the thing, the interview went so well that the HR explained all the benefits for its employees and handed me a copy of a leaflet containing so. In the end, as they were walking me to the door, the HR lady told me "you are staying here, you don't have to look anymore" as they were walking me to the door.

Well, everything I did from my end was perfect. Thank you emails and follow-ups blah blah. But not a single answer from their end regarding any decision.
This was the worst feeling to me.
