Meta Software Developer interview questions

After being contacted by the recruiter, I had a technical phone interview, and was then flown on-site for a detailed interview. The overall experience was excellent, with enthusiastic, encouraging people. All accommodation and transportation costs were covered. The interviews were of one of the following types: coding, cultural fit or architectural design.

A recruiter has contacted me through linked-in, asked whether I'll be interested to work for them, then had a talk about why would I like to work for them and I replied: that I would like to work with the best engineers. Afterward I had a phone interview with some engineer, asked me to write binary search, when I finished, he asked me to write binary search on a shifted array (10 20 1 2 3 4). Wrote that and then asked me to find the offset (2) in log n. I guess I did that ok and then I was invited to onsite interview.
