A questionnaire with some technical and background questions, followed up with 5-6 interviews with various staff. Had great resources in their handbook which helped prepare for each stage of the process. As discussed in some other posts, the process took quite a while, as this is a completely remote company dealing in multiple time zones this is pretty understandable, I also applied just before the Christmas holidays, so a lot of the team then was unavailable when I would have interviewed. I would say of all the companies I interviewed with they had the most well prepared common sense methodology for screening and interviewing people.

The interview steps were exactly like described in the team handbook. Before first interview I was given a few questions to answer, it was to assess my interest in the role and how well I match requirements - some sql, STAR questions, why Gitlab and if I joined what I would like to work on. Then followed by HR interview, Manager interview x 3, peer interview x 2, background check and references. The communication was very good throughout the whole process, general experience was very positive
