I was contacted by Louis who is one of the data scientists at Agathos.
I had technical phone screen with him first followed by a take home. These two steps alone took more than a month. Their hiring process is slower than other places.
The take home was not documented very well but it would give you a feel for what to expect at the job if you were to take it. Louis took out the time to provide feedback as where I didn't meet their expectations, which I appreciate.
