Emma interview questions

I was contacted after passing a test, which was reminiscent of tests done back in the early 2000's. After contact I was informed that I would receive a link to book a time for an interview shortly - that did not happen I had to send an email hinting politely at the fact it was not sent. When I receive said link, I booked a time and it said I would receive an email with Teams link shortly. It's the day before my interview and nothing has been sent and the person who is handling it is out of office until the day of the requested interview time. So far not impressed with recruitment process and will most likely remove myself from it.

There were two interviews. Each interview consist of 30min personal motivation and 30 min solving a case + brain teasers. Case: How many mattresses are sold in Belgium per year (market size)
