I talked with some Indian guy, seems to be HR specialist. Questions was pretty common, also he asked me for desired salary, I answered 7K$/month would be good starting point. No any feedback after that call

Long, and poorly managed interview process. You go through several technical rounds with engineers, managers and the co-founders. expect them to be late, unprepared and have little idea who you are or which stage of the process you're in. Throughout the process they'll keep lowballing you. Even after you pass all the rounds, they'll come back with an offer that's lower than what was originally discussed. It feels like they deliberately drag you through multiple rounds only to cut compensation at the end. They expect long term loyalty and "commitment", yet offer below market pay and treat candidates with little respect. Avoid, there are better companies out there that are not trying to take advantage of LATAM talent by paying them as little as they can.
