Anyway, I have just received the eagerly awaited phone call. I'm through to the next round; they said they were very positive they wanted me, but...the selection committee chairman who gave me the news also said that they had two caveats:
He told me that they will place special emphasis on gauging how I perform in a team during the assessment round, because the work I do at HP at the moment does not appear to them to be so much team-related. Fair enough. I'll just read up on working in a team in the next week or so, and see if anything sticks in my mind.
He also said I could have prepared myself for the interview better, and it had been a special point of concern to him personally, but that I had redeemed myself by making that remark to the next interviewee that I could have done better if only I'd taken more time to read up on things.
But who cares?
