The process took almost 2 months in total: 1 HackerRank challenge and 3 interviews (1 in-person).

It consisted of an initial contact by email (3 weeks after applying) to inquire about salary expectations, where I live, and to inform me that if I were hired, for the first 100 days I would need to go to the offices twice a week (near the DOT).

Then they sent me a HackerRank challenge, which was an app (Meli's item listing) and I had to fix errors and implement functionalities.

After passing that, I had an in-person technical interview with the project leader and 2 team members. There were several moderately basic theoretical questions and a programming exercise to do on the computer.

Then I had an interview with Talent Acquisition, who told me a bit more about the position (not much more, honestly).

And finally, I had the interview with the Software Leader.

In theory, after all of this, they should have asked me for references from a former leader and a former peer, and later made the formal offer, but I didn't reach this point because they chose another candidate.

Saying it's the Virtual DOM and the DOM. REST principles. How to scale vertically and horizontally. What is a promise.
