I applied at around the end of December 2020, then I got an invitation for math test at Jan 11. It was an online math test with 20 multiple choice questions in 20 minutes. The math test was similar to TPA SBMPTN questions I believe, kind of HOTS math questions. Make sure you stand by checking your e-mail after the math test because there would be a following interview with the HR at around 4 pm (I almost skipped it because I didn't check my email!). Fortunately I could join the group interview with HR, there were around 6 candidates and the questions were very basic like self introduction , how soon we can start, where do we stay. Then I passed this, the next interview was with the user from the product category I was assigned. There were me and another candidate in the user interview. I got the offer at around 8pm after the user interview.
