As an employee I almost resigned the first week at a startup but convinced myself the bad vibe I was getting was an overreaction. It wasn't. I ended up resigning within six months. As an occasional hiring manager I would prefer a candidate reject my job offer as early as possible. First, so I can revisit the other candidates and hopefully not have to repeat the entire process. Second, if the new employee quits, it's more expensive to restart the process six months. I don't know German employment law, but in the US you would have no obligation to the employer unless you've accepted reimbursement already or signed a contract of some sort, and even then you can usually work out not takng the job.
