Crossover for Work interview questions

Before the one-on-one interview, I've completed 7 different online exams. First one is Basic Fit Check took 5 minutes. Second I got Cognitive Aptitude test. Third one tested my english speaking. Fourth is for SQL knowledge. Fifth is for Complex Problem Solving in code. And finally I got an assessment about Defining Engineering Work.

I applied online with a CV and tailored cover letter and some hours later received two automated emails asking me to register online. I have never heard of such a time consuming hiring process as the following. Listen to this madness. First you create an account and watch a short video where it says they only hire the top 1% of people and basically pride themselves on putting you out. Then they want you to do a skills assessment for 2 hours 15 mins and THEN "real work assessments" for 4 hours!! Then, presumably if they like you after a whole day of labour doing that, they interview you. Salary is listed in USD but was visible to me in Europe, there is no conclusive word about whether they would be able to hire me from my region anyway. There is no company I have EVER heard of that wants you do do so much unpaid labour before interviewing you, and this is a huge red flag. The listed salary of $100,000 for a content writer position also sounded too good to be true so I declined to go further. If the hiring team are reading this, I would advise an interview first, then if you are serious about proceeding, all the tasks. And pay people for their labour. If not, that level of free work is exploitation.
