Unorganised company. - Senior Software Engineer Deep Vision Employee Review

Very disorganized company: They shortlisted my profile and called me for an interview. I cleared 3 technical rounds successfully but in the 4rth they realized that I don't have the relevant technical expertise(embedded) that they need. They had my resume and I already told them that I am a pure backend developer. Thanks for wasting my time. After that, they called me and apologized for the same.
