I applied online for a Software Developer role (mid-senior). It is a 4-stage interview process.

I had the first phone interview with HR, who was extremely helpful. It lasted about 30 minutes and covered my experience and my reasons for choosing this role and company.

Then, I was given a code test before proceeding to the next stage.

The test was online via "Codility." I suggest candidates train on it for a few days or a week before taking the test. Also, be aware of the complexity of your code, as it significantly impacts your score.

I had 4 questions to complete in 2 hours:

• Integer manipulation (easy, 20 min)
• Bug fix (easy, 15 min)
• String manipulation (medium, 30 min)
• Problem requiring data structure and algorithm thinking (hard, took me 55 min)

I then had a Zoom meeting with the manager. We discussed my experience and their needs for this role. He asked me some theoretical questions about the language and data structures in depth.

Unfortunately, I did not pass to the last stage. They informed me they had accepted another candidate who was a better match for the role (only one position was available).

Overall, the interview process was great, and the HR team was very professional and kind. I also enjoyed preparing for and passing the code test. I will try again in the future.

How a specific data structure works. When it's good or bad to use it.
