Meta Software Developer interview questions

It was 4 interviews in total with a lunch break in the middle. Two interviews are considered to be conding, one disign and one cultural with a little bit coding. Overal algorithmic problems on the interview were pretty simple. But they pay attention to implementation details, make sure that code actually works properly for all the cases and try different test cases.
