I'm preparing for some interviews. Being a freelancer I don't have many data points. If you ask people directly no one tells you anything. Glassdoor doesn't have enough information about startup companies.
So what is a reasonable salary for a backend engineer with 5+ years experience at a Berlin startup? Minimum, maximum, median?
He is doing 40k € + relocation (around 2-3k) + bonus.
Bonus depends on the startup.
