They contacted me by email. We arranged a short interview, where they described the job and the company. They asked me to do an assignment at home. I had to develop an Angular project. I successfully completed it and never heard from them again. Terrible behaviour for such a company. They did not even thank me for taking the time to complete the assignment. And they did not send me a rejection email. The employer shines at the rejection stage, not the hiring one. Stay away from them. There are many employers who care and will invest in you.
