I was contacted by the software project manager directly.

First the call started later than original time, but I understood the interviewer might be busy at work so that is fine.

I had a phone interview mainly on some background and describing past experiences.

The interviewer said the next step is to move on to an online test.

Instructions given were not clear and no meeting invite sent. We did agree on the date and time during the phone interview but in the end the interviewer just ghosted when the day came. I tried to contact the interviewer via email but there was no response.

This interview process is just very unprofessional and is the worst interview so far.

Please describe your resume and background.
