After several days I received an email asking me to complete a very thinly-veiled IQ test. This test takes roughly 90 minutes and you can only really take a break of any kind in the middle between the two parts. I felt like I done pretty well on it but found it very offputting all the same. Two days after completing the test, I was told I had passed and would be forwarded to the next stage, the day after that I was told that I didn't match the requirements (this is presumably due to the gap since I graduated, during which time I was doing an internship, there isn't really anything else that didn't fit the role). It's pretty hard to not be negative about a company who automatically asks you to complete a fairly time consuming challenge before they even glance over your resume.

Asked various theoretical questions, mostly focusing on things to do with data. Asked questions about efficiency and how you would ensure it, as well as asking what experience I had with testing
