I applied through Linkedin, was interviewed the next week. The interview went okay, but 2 weeks later, the HR called and asked when I can start working for them (totally ignoring the fact that they have to first, offer me a job, and I needed to serve notice period for my old company). She expressed her "shock" and displease when I told her I haven't quit my old company yet. After that, they ghosted on me despite my repeated inquiry email. Overall a very unpleasant experience, just to show how unprofessional they are.
