Poor compensation - very learn business that keeps its cash for product promotions (referral bonuses) rather than employee compensation and irregular share bonus scheme (shares are still on paper).
Like many mid-sized company suffers from cons of both a smaller company (unclear strategy beyond copying the big companies - "company X is doing this, company Y is doing that", many inexperienced middle managers (early joiners) who love to 'flex' by asserting goals that do not have a clear strategy behind them) as well as those of a large company (lots of red tape due to wanting to be a bank, insane politics).
Very little product leadership and high engineering staff turnover makes it impossible to keep a steady roadmap. You risk learning bad product habits that should not be transferred beyond this company.
Most people have not come from a tech background, but rather banking or consulting, carrying over the exact same culture.
