1) One hour basic python scripting skills. Like string manipulation and for loop basic. They used coder pad. 2) Three One hour 2:1 interviews that were both technical and behavioral. Cool part was the two people who interviewed me each time were actually people on my team. 3) One hour algorithm challenge which was super basic. Personally I liked the people but I went I got this with an offer on the table already and told them I needed to move fast. After they drug it out for three weeks I got pissed off and sent 7 emails in 2 days insisting they make a decisions and extend an offer or walk away. They did a really poor job of setting expectations and communicating. I would work here but it really is one of the worst interview processes you can imagine.
