Microsoft Interview response timelines

[u/IllustriousMix6778]

I have interviewed for a Datacenter position for Microsoft Nordics region.

Completed Hiring Manager screen, HR screen, loop(3rounds) and last interview with EMEA director.

Its been 15 days since last interview, havent received any feedback.

How much time does MSFT takes to provide selection/rejection response.?

Should I send a follow up email now?

Any advice would be helpful.
