Quick communication, though their CTO is a clown. He's been assigned with searching for the unicorn: UI design skills, React, Swift, Kotlin, Golang, Java, Microservices... It's really bad to waste your time on interviews and assessments, only to find out that they actually seek someone who is expert on every domain of software evelopment that exists. Fortunately, they didn't ask for ML skills. Follow the job description, you will find everything in there. Don't waste your time on funny companies.

I reached them through LinkedIn, and there was an automatic interview about programming skills, after that I passed two screen interviews, they made it a good experience. Unfurtonelly I didn't have the years of experience required . .. but they were always telling me the status of my application.
