I submitted my application on 31st December 2017 and was invited to an online test a day before it took place January 11th. The test had 9 questions that had to be answered within 20 minutes. The difficulty I would rate as average. The questions were general and there were a few questions on algebra as well. I was later made to understand that algebra questions look at decision making, which makes sense.

i applied through the website of the company and it take 2 month to reply i had written test and just about simple IT also h have a second around test and then an interview it was easy
