Smooth, the recruiter offered guidance. The level of difficulties was about medium easy. You might get stuck but just ask for hints. Usually if you passed three questions each you would pass.
I applied online. I interviewed at Meta (New York, NY)
Interview
Prepare technical concepts, and practice previously asked questions as much as you can find online. 4 rounds in the total process. It's easy as long as you just practice a LOT.
I had Python and SQL round for 30 minutes each. The interview was for 1 hour 30 minutes for SQL and 30 mins for python coding.
Completed 5 questions each but still got rejection email the next day.
