Received irrelevant multiple mails and calls from recruiters for the hiring process.

I passed the assessment skill and HR scheduled an interview ahead of the day I chose via the portal. But on the day of the interview, I got a mail saying that the interview was cancelled. I tried to contact the HR over phone and mail, but there was no response. I still contacted over the help line number, and the receiver said that there is no requirement and I have to wait.

Very unorganized and messy process.

The assessment test had questions related to machine learning and visualization libraries on Python.
