SingleStore Software Engineer interview questions

Contacted trough angel list, went through the following: 1.) 1 hour coding challenge (ssh into machine and complete task) 2.) 1 hour coder pad interview 3.) 1 hour algorithm (non coding) interview 4) 1 hour hiring manager interview 5.) 48 hour take home project (supposed to take 1-2 hours and instead took about 4). All of this took place over about 2.5 months. I thought the team was friendly, but the process was too drawn out.
