I'm gonna hold off on breaking out the champagne, at least for a day. But, thanks everyone for the support! :tiphat:
First of all, it sounds like you did well in the interview. Congratulations.
This comes from one of those IT drones at GS.
Anyway, it is wrong to over-analyze an opinion or statement from an interview. From my experience and other cases, decisions are not taken so easily.
Also, if the position was in Technology, then it matters little if one interviewer sees you suitable in another area. He can recommend you, but unless he has a close link with a quant oriented team (e.g. Strats, High-Freq, Alg Trading), it means very little.
Furthermore, "quant" is a buzzword often used, it doesn't mean that you are working directly in quantitative finance. Some areas consider quant as pure analytics or metrics. They can report on trade volume or other metrics.
Do you know the business area/desk they are refering?
In the set of interviews with the other department, you should try to understand as much as possible what they do.
