The whole process of joining Northcoders happened in a bit of a flurry in mid-February. I had been scouting out bootcamps for a little while and had my eye on perhaps joining a remote coding bootcamp, which was about all I could afford at that time. Then I came across Northcoders, which looked quite new, and because I couldn't see their fees on their website, sent them a tweet.
I won't discuss what exactly the test was - but the logic felt pretty complex (for me) and at points I felt like I didn't know what I was doing and was just guessing what would work. I felt increasingly disappointed in myself as the challenge went on and thought I was doing really badly, but James and Chris actually said I'd done well once I got it working. Thinking about it, I guess maybe what they'd really been looking for was not whether I knew the solution immediately, because that was hard, but how I'd think about getting there and whether I knew my basics. Maybe they also wanted to see how I behaved when I struggled or thought I couldn't do something - I don't know. At the time I was just so amazed to be offered a scholarship that I promptly put all worries to the back of my mind and went out to buy a new pair of shoes to celebrate. Later, I began to think about the challenge some more and slowly the logic began to make sense. I could see clearly what I hadn't been able to see in the heat of the moment and wished I could have taken a step back to pause and look more carefully at the problem instead of rushing through, worrying about taking too long.
If you are going for an interview for a bootcamp, I would recommend brushing up your skills as much as possible - because why wouldn't you be doing that anyway? - but perhaps more importantly, remember you're not supposed to know everything. You can trust that your interviewers know what they're looking for and how to test for it, and you can be sure they are using the coding challenge as a way of testing more than simply whether you know the answer to X problem. This is their chance to see how you work, how you respond to challenges, how you find help, what you do when stuff doesn't work, what questions you ask. They definitely want to see you succeed and not give up, even if it takes a while, and a bit of googling!
