The process was very streamlined. I applied via their website and was immediately sent a link to HackerRank, a one-hour coding challenge.

I did the challenge soon after, and on the same day, I was sent an email and offered an interview.

The first interview I had was over Skype with the recruiters, which involved a few standard HR questions like "Why do you want this role at Atlassian?" and "Tell us a bit about yourself."

The next stage was a set of three back-to-back interviews, each about an hour long:

• A whiteboard/design interview where I was asked about a system I had previously worked on.
• A technical interview where I was asked about my computer science and technical knowledge.
• A coding interview where I was asked to implement a simple data structure in Java, with tests and benchmarks supplied.

Later that week, they followed up on the interviews, and the next week I received the offer. I was given a week to accept.

Overall, I was very happy with the process, especially with how prompt they were relative to other comparable firms. I was also happy that in each interview, I had the opportunity to ask my interviewers about their experience with the company.

When should you use a linked list versus an array?
