AliveCor interview questions

I applied through LinkedIn and Got an Initial Email to schedule a phone call, the interviewer asked few basic questions: Tell me about yourself. Why do you want to work in the company? Are you familiar with the company's background? Salary expectation? Where do you stay? Do you have customer support experience? Do you have any questions for me? after all this she asked me for my availability for second round. but later the same day in an Hour, I got the mail that they found someone else more suitable for the job and they are not moving forward. Strange :/

When I decided to join here, I didn't receive any updates about the joining process. This was after being selected for the IT Specialist role and receiving an offer letter from HR. The whole process wasn't engaging. After contacting the hiring manager for the status, he also ghosted me a few days later. It is never a wise idea to trust anyone in this company; their words can be changed at any moment.
