I applied through referral, and interview with Hiring manager went well, however, my candidacy got declined. I received great feedback about the reasons of that, which was a great learning opportunity for me.

Comparatively lengthy ~3months but smooth well organized process. I was given detailed and helpful information to prepare each round of interview. It's a pity that they do not interview you simoultaneously for similar role with different teams and could sometimes take a while to receive a follow-up after an interview round.
