Hi misokatsu, I applied to the ai track. The interviews were done like 3 weeks ago. Since you mentioned that u just had an interview with DBS only last week, I guess they will probably finalize by end of this week or even next week. Bear in mind that they really have many candidates to interview. Their hr people are working very hard these days.
If the fi is going to give an offer or rejection, it will be done through the ibf. Thus, if u really want any update, you can email IBF. Usually it takes about 2 days for IBF to return email. IBF staff are also very busy during this period.
Wish you all the best and hope the right offer will come soon. Cheers
