The application process began with online tests, which were quite difficult. I'm not sure how I passed them, as they were by far the hardest numerical tests I'd encountered, with a very strict time limit. I timed out and had to email them to re-open the test; it times out if you do not answer a question within 2 minutes.

The video interview was next. There was nothing out of the ordinary here; knowing your role and experiences should be sufficient.

The assessment centre was a long day. Be collaborative in group exercises and aim to find all possible solutions. During the group exercise, individuals are taken out for one-on-one interviews. Be very clear with communications while this is happening.

For the one-on-one interviews, show what technology you are interested in, relate that to IBM, and demonstrate your passion for technology!

For the other logical group exercise, communication is key. Make sure you time check and have someone drawing out the logic on the whiteboard.

The tour was fun, followed by an informal chat with the graduates.

One more individual exam was required, with 20 questions. It wasn't as hard as the online tests but was negatively marked, which I didn't realize at the time, so I guess I guessed well!

I may be mistaken, but I believe there was also a presentation, which was nothing to worry about as it was only one-on-one.

I passed the assessment centre and was then told I would hear back about a team, etc. This was six months ago. I suspect they forgot about me. However, I had other assessment centres and interviews and found a job more suited to myself, so I never followed this up.

Brush up on current tech and why you find that interesting.
