Due to certain circumstances I had asked for a telephonic interview. Things were great initially, Interviewer were on time, it was going great, suddenly there was a fir drill they said they are done from their end and would let the HR know about my feedback. I mean how could you be done in between of your questions? Rather you could ask to call me back later. Anyway, Since then I have been following up with the HR as not sure if the feedback was positive or negative. Although a reply mail would have been nicer.
