UBS Director interview questions

Initially spoke with the hiring manager who was very pleasant. They asked detailed technical questions about my experience and how it would apply to job requirements. All in all, went well.

Initial communication was so enthusiastic and HR themselves contacted two three times and asked to apply. 3 rounds were there. Despite follow up, have heard nothing from HR for more than 15 days. Not expected at such senior level for a company like UBS to have this unprofessional behaviour when it comes to hiring process.
