UBS Applications Developer interview questions

Hiring was for Mumbai(Airoli) location, but interviews were taken at Pune office. (Cabs were provided) Firstly there was a online test, who cleared it were called for Face to face interview. At their office, there were 2 technical rounds. First technical round was more aligned to core Java concepts and oops understanding. Second technical round was mainly on ability to derive best approach for given problem statements. Post which HR discussion was there, which was just a formality. Next day I got a selection mail, asking for some documents. Don't know what happened in between but I received a next correspondence mail from UBS after 2 weeks containing salary and terms which were no where near the one discussed with HR. Thereafter multiple telephonic salary discussion were there, which came out fruitful and I was promised a confirmation mail within few days, now past 1.5 month I got a sorry mail from UBS.
