CarGurus Software Engineer interview questions

The company recruiter contacted me on LinkedIn with a job opportunity. We scheduled an initial interview. He did not call at the appointed time, nor did he offer any explanation. This lack of professionalism reflects badly on the company. I wonder what else they are saving on besides cheap recruiters...

After an on-site interview, they told me they wanted to hire me but didn’t have a job just yet... and strung me along for 3 months before ghosting me after the recruiter (their recruiter) I was working with left the company.
