The first step is not "to know each other" but the tech task. Boom...
Classical crapy task:
- they expect you to do it in 4 hours
- even with the doubled time it's pretty hard to do task in a good way
So the are a few logical questions:
- why do they force devs to do crap?
- do they really want to review a crappy code?
- or do they want devs to spend more time than requested?
No alternative (for this task) was proposed.
Also, they respond suuuuuuuper slowly. Not sure they deserve to call themself a "startup".
As a resume: I do not recommend even applying. Do not waste your time.
