Meta Data Science interview questions

I wish there were more to describe, but this is mostly just airing a grievance with Facebook's recruiters. I had a recruiter reach out to me about a month ago for a Data Engineering job. I'm not a data engineer, so no problem, but I had a friend who's at Facebook drop my resume in for a position better suited to my background. I received a rejection email on that position. No big deal. Happens all the time. Last week, another recruiter from Facebook hit me up for a data science job. I said "Hey wait, my friend put me in for a similar position a couple of weeks ago. I think it'd be pretty unfair if he didn't have an opportunity to receive a referral bonus." She reached out directly to my friend and asked him to submit my resume again for this Data Science position and then scheduled a call with me for today. A couple hours before our scheduled call, I received a rejection email akin to the one from a month ago. I replied to the recruiter who sent the rejection and said "Hey wait, I have a call scheduled for this afternoon. What's going on?" and she replied that there was a matter of a duplicate record. Then the original recruiter who had reached out to me totally ditched the call that we'd scheduled. I can handle the rejection. Again, happens all the time. They have something they're looking for and I'm not it. OK, no problem. But the absolute, total, incredible lack of professionalism from Facebook Recruiting is just embarrassing. I will _never_ respond to another Facebook recruiter. On the off chance I actually _want_ a job at Facebook, I'll work through my contacts and avoid their recruitment people at all costs.

I’ve only started the process with them so only did the telephone interview. The recruiter was kind, asked me about my previous experience and told me about the position. Asked a few analytical questions.
