Got a job offer, red flags and is this even legal?

So, to set the scene I’m currently looking for a job in Germany an had a few interviews with different companies so far.

One in particular was very fast to get the process started and was not very interested in my abilities or what I have done before and so on and this is the company I want to have your insight here, please.

It started with an HR interview and I thought it went well, they talked about a huge salary (75-80k per year where as the average is around ~50k), an additional bonus program (10-40k max per year), fast promotion if you do well and pay increase with the promotion and basically heaven for everyone applying to this job. (I should have been suspicious here already) After the HR interview, they gave me a task to evaluate how good I would be in this job. I did it fine and they invited me to the next round.

The next round was with a team leader in the company and we talked again about salary and bonuses and so on. This time the team leader told me it would be slightly less base salary as the bonus program is so good and so easy to get the bonus and told me about all the conditions for the bonus and so on. Also, there is no home office, only if you are a top performer and then Monday and Friday are not allowed so you don’t slack off. It sounded a bit weird and off compared to what HR was telling me. Anyway, the interview went well and I got the contract yesterday.

The contract shocked me a bit because they offered me “only” 50k per year as a base salary and the bonus program was half (5-20k per year) as well. Then I started reading the contract a bit closer. It is basically not in your power to get the bonus consistently as it depends on the client, the group manager and some other 3rd party.

The next fascinating fact is that you have to take 50% of the bonus that you make and reinvest it in the company. Basically, you have 30 days to buy stocks (they are not yet on the stock market but want to get there) and show proof you did it and in the case they go public you have to give all your stocks to a 3rd party to hold them for you. And you are not allowed to sell those stocks for the next two years .. (even if you leave the company) Is this even legal that they force you to buy stocks? And ofc you have to pay all the fees.

All these inconsistencies and other funny contract clauses sound very fishy to me like they hire you to burn you out and milk your bonus from you.

It sounded all very good in the beginning but now it sounds so weird and like it could mean a lot of trouble. I’m not really considering taking this job anymore but was wondering if this is something normal and I’ve just never seen this kind of stuff or if this is really just kind of a scam.
