IBM Data Science interview questions

A very bad experience: I applied online. After a week to two weeks I received an update including congratulations message that I passed to the next recruitment stage, where I will be asked to complete ONE or MORE of assessments so that they can learn more about me (and I am quoting). I just had to declare whether I have a disability or not to customise the assessment for me. So after I declared a message was displayed that the assessment will be sent to me. Surprisingly, 2 days later I received a rejection email without receiving any links for the assessment!. I sent a couple of emails but I get a failure mail delivery status and I couldn’t find any other way to communicate. For a company this huge, a 100% fail!
