I applied on LinkedIn in June 2020. The process took 10 days, I was invited to the initial interview, which was cordial and typical. The next few days I was asked to provided availability for a second interview, which I did, but ended up not receiving any response. My advice: If you mistakenly selected a candidate for a second interview, it may be more decorous to own up the mistake and let the candidate know, especially during the COVID lockdowns. Communication is the key to mutual respect here. I am glad that I never proceed to working with such a team.
