I took their generalist test and scored perfect. It was actually not so hard, but it tested some language things (a couple/few languages), some Unix things, SQL, etc. It was right up my alley.
After completing the 30? min test, I got an email saying they were enthusiastic about me and would like to continue the process.
I think the process was to become an interviewer; I forget now.
Time passed... weeks, and then months. I emailed them and got nothing back.
Then I checked Glassdoor (YMMV). There were a lot of negative stories about internal politics, gender issues, leadership problems, "insane" bad manager stories, etc. I don't know how Glassdoor works, but perhaps it was all lies; or perhaps it was very true; perhaps it has been erased (pay to play).
Nonetheless, I parked them in the corner of my mind behind Toptal.
I didn't even get the "privilege" of doing the 40 hour take home project (which culminated in a formal business presentation that some people reportely failed despite turning in a polished project".
Later I found complaints of Toptal members that they were pressured to provide low wage offers to get gigs.
Overall it felt like perhaps an ernest initial effort to make a better system and a quality consulting firm, but it got perverted into a heartless profit machine. I'm glad I didn't progress to the 40 hour take-home stage.
