First of all - some new joiners were "actively encouraged" to leave good reviews on Glassdor during their probation period lol. You should check if those 5 star reviews are by people less than 1 year at the company :)
Bondora has around 200 people, out of which ~10% are C-Level (which I find really high) and they micro-manage EVERYTHING.
Especially the CEO needs to get involved in everything and give input on all levels of the company.
For a while he was acting as head of product, then as head of legal, then as head of investor product, ... and he actively funnels decisions through himself.
Every 4-6 months, the company is re-organised and a bunch of people get fired: We are a marketing company, we are a product company, we are a tech company, [...] and then it goes back to where we were 18 months ago.
For any bigger decision your manager needs to get feedback from CMO, Head of People, the barber of the chief accountant, the car mechanic of the CEO, the golf buddy of the CPO and so on.
Then the C-Level decides something behind closed doors over the next 2 to 8 months and then just announce via slack what they came up with and everyone else needs to reshuffle.
Your team will never have enough people and every year the targets just go up, bunch of people burn out.
Colleagues are only backfilled if your manager pays for it in blood but the expected output stays the same.
The whole HR team quit one by one over the last 6 months and that tells you everything you need to know about this company - not even the HR people like the people culture and that starts at the top.
A lot of people really feel like they could get fired any moment (you regularly see cold "We would like to inform you that X had their last day with us today" posts in slack) and that affects the team spirit a lot. So if you plan to build a house and have a mortgage, maybe look for something more stable.
