Got referred by a friend working in TransferWise.

First, you will need to complete an online Hackerrank Test. The test duration is 90 minutes.

It mixes MCQs and Coding questions.

• MCQs are in the domain of OOP and a few common engineering knowledge.
• Coding questions have both Algorithm and SQL.

All are mid-level, nothing too difficult. Get yourself familiar with Hackerrank beforehand, and you should be fine.

Next, the recruiter will have an initial chat with you for 30 minutes. My recruiter was friendly and professional.

The next round will be an onsite technical round with 2 engineers for 90 minutes. We went through my background and the systems that I have previously worked on. We did 2 algo questions, again, mid-level; your thought process is what matters here.

If you pass the technical round, there is a product round after this. You will meet a PM and discuss your thoughts on product development and decisions in general. The round can be pretty fast; mine lasted 30 minutes.

The final round is a Tech Lead round, where I met 2 tech leads. It's like a combination of both technical and product rounds. My impression of the tech leads is good. They do have a very deep technical knowledge base, based on my discussion with them during the interview.

I got an offer a few days later. The recruiter will schedule a Zoom meeting with both of the team leads above to go through the offer and the detail of my position with me. This is a very unique experience, as in other companies, normally recruiters will just call you to announce the offer.

Overall, I feel like TW really cares about each candidate and is willing to spend a lot of time and attention on potential candidates.

Mid-Level Algo Questions. As long as you practice some LeetCode Medium questions, you should be fine.
