Pros
SEMrush is an amazing company to have on your resume, especially if you're looking to make a career in the tech industry. There are opportunities to travel all over the country and maybe even the world, go to conferences to help you grow and learn in your specific field, work with people internationally, and learn from some of the best in the business. There are also work from home days, which is great. SEMrush is pretty lax environment as long as you work hard and don't slack off. You also get to work with really great co-workers who will turn into friends.
Cons
A lot of the management is in Europe, so it can be hard to get a hold of them during US business hours. The company prides itself on having a "flat-structure" but it's not really, we're a US company that is still using European culture values - this has to change.
