I was contacted by a recruiter for the opportunity at Udemy. The entire process took about 3 weeks.

An initial phone screen by a recruitment manager was followed by a technical phone screen. Then, I was brought in for 5 rounds of onsite interviews at their SF office. I was asked OO design questions, SQL queries, Django framework questions, and JavaScript language specifics.

The interview process was a bit messy, as some of the interviewers weren't sure what position I was going for and whether anyone else was interviewing me. No one communicated with me after the 5 rounds of interviews were done, and I had to wait out in the interview room until someone eventually came in and said I could leave. Thereafter, it was radio silence, and I never heard back from the company.

I do expect to be informed of the outcome of my candidacy after spending my time going onsite. This is not professional behavior.

How would you design the game 2048?

Explain JavaScript closure and variable hoisting.
