Meta Data Science Manager interview questions

The process took 3 months . 2 screening interviews, 5 interviews and 2 follow ups . In total 9 interviews . Two of the interviewers were very disrespectful. One was chewing gum and the other one was yawning on my face and checking his phone without even apologising . In the end , the yawing guy that happened to be a director rejected me . The recruiter took ages to come back to me and suggested me to apply again in 6 months. Do they think that every 6 months I will be interviewing for 3 months and having the risk meeting people that do not respect candidates? In addition, no one even apologised to me.

FB recruiter reached out looking for senior person to fill leadership position in new office. Intro call with hiring manager, then on-site with eight different team members and more senior people. Very FB-product focused, surprisingly homogenous group who had spent most of their career at FB.
