Interview process was ok. They have arranged the cab for all candidates to reach the destination. Number of rounds = 4 1- Online test 2- Technical interview 3- Technical interview 4- HR (salary discussion)

But real problem is after clearing all round, HR will send you mail where you have to submit all the documents. Then HR will say she will release an offer letter within next 2 week. But she will not. Then nobody from UBS will bother to give you a call back or send status (not selected / selected). At least send the status mail so that candidate will get know they have to move on or wait for the offer.
