Almost exactly one year, one month later I left the company with no promotions or stock options in sight, although the workload and my duties were significantly larger than we agreed on.
In addition, that year made me realize that I had absolutely no passion for the work I was doing (automotive industry) and while the startup culture looks glamorous, it's far too stressful in the end and negatively affected my emotional and physical health.
I'm back in "big corporate" fintech and happy to say I was able to bring a lot of what I learned in the startup world back with me. I've been advancing my career far faster than I would have done in the land of startups and now own a significant amount of stock in my current company.
