Meta Data Engineer I interview questions

I applied to Facebook a while ago, and someone from Facebook reached out to me some time later. It wasn’t regarding the position I applied for, they had my information already in the system and reached out in case I was looking. It happened I was actively interviewing also with other companies. The first conversation went great, we talked about my background, what position entitles and some technical question. At the end of our conversation, the person that interviewed me told me he will speak with his team and get back to me “tomorrow”. Mid time I’ve received an email to sing up to Facebook recruiting website, I was sent test prep materials, and was asked to pick my availability dates for next interviews. The person that interviewed me didn’t get back to me the next day, week, or month. I received an email to provide my work authorization and nothing after that. No email, phonecall, note, on recruiting site still shows “your conversation took place recently, you should hear from ur shortly”. It’s been 3 months, I haven’t heard anything, not even an answer to follow up email I sent. It was the most unprofessional experience I’ve had. Every single company I interviewed with gave me an answer or some kind of follow up. Thankfully it didn’t work out, I landed position elsewhere with amazing company.
