Lack of transparency in the hiring process. There was a good amount of bad hires which could have been prevented if the rest of the team was involved. However, they didn't think it was necessary for a small company to get along with the other individuals being added on. This greatly affected the teams morale.
Lack of merit-based promotions. Promotion seems arbitrary, hard to project individual growth trajectory within the company.
Overall, the company is not scaling well. The company is still considered small but we're being asked to do unimagined tasks without any room to fail. Be prepared to jump off a cliff because there's not gonna be any cushion waiting for you. High velocity, low burn? More like high velocity, high burn. You would see your team mates burned out left and right.
Is there a learning culture? Sure, maybe the initial trainings in your first week or month but afterwards, you're on your own. Make a mistake and be prepared to be flamed and belittled like a child. You'd start to question your career and placement in life. How's that for career growth?
