Canadian Solar Project Manager interview questions

A recruiter reached out to me on LinkedIn about a project manager job they thought I would be a good fit for. It seemed suspicious they wouldn't chat on the phone and only suggested apps like WhatsApp and Telegram. I asked if we could use google meets instead and they accepted. They took days to respond when I asked when they were available, and they simply responded with "now". I once again asked if we could schedule a time, and sent them a date and time and confirmed the time zone. They agreed and accepted the meeting invite, only to not show up come the interview time. One of the most unprofessional recruiters I have come in contact with. They had poor spelling and grammar, poor communication skills, and frankly did a very poor job of representing the company.
