BairesDev Scrum Master interview questions

I applied for the position on LinkedIn. In a few days, I got an email asking me to complete an assessment. There are about 12 assessments. Most of them had nothing to do with the position. I eventually get around to completing 3 or 4 then I get an email scheduling an interview. The day before the interview, the recruiter sent me a HR form to fill which I did and sent back immediately. About an hour before the interview, he sends an email asking WHAT POSITION AM I APPLYING FOR?! We had scheduled the interview almost a month before that day and the scheduling software asks what position you are applying for so it's right there. The interview gets cancelled with a promise to share my details with another recruiter within the company. About a month later, I get a phone call asking if I am still interested in the position. An interview is scheduled for the following week. The day befor the interview, the recruiter cancels the calendar invite then sends me an email that the positions she intended to interview me for have been filled. Wasteful, mismanaged process.

I went through 3 steps: the first one was an HR interview, the second one was an English test and some math problems and finally, I had a technical interview.
