First recruiter screen
After following up a few times, a phone interview was scheduled.
Phone Interview round
Nothing too difficult, the questions were around real world feature builds.
If they tell you it's a coding interview, don't think it's *only* a coding interview.
In my interview, there was some design aspects which needed to have been decided ahead of time. There were 2 ways to update data, and 1 "shortcut" introduced without clarity as to what would happen to the stale data.
Design LoyaltyLevel feature for users based on number of visits. Persist family accounts where members go up in level when their family member reached gold.
Catch - when members go up in level, number of visits don't increase. Clarify design requirement with interviewer.

Entrevista
I had a call with their recruiter first, talked about my past experience and what I'm look in for in my next role. Then had a technical front-end screening with two engineers where I needed to build an application. I thought I did well, I was able to implement a working app, but I did not pass. Not further feedback was given.

Implement a memory game in any JS framework or vanilla JS. You need to implement this game based on some demo app that you can play around with before hand. You need to implement the HTML/CSS and JS all from scratch. The game has the following behavior: you need to display N x N cards in a grid lay out. The number of N should be configurable by the user through a slider. When the user clicks a "start" button, N cards a highlighted for 2-3 seconds. Then the user needs to click on the cards that were highlighted. If the user clicks on the correct card, it changes the color to green, otherwise it changes to red. If all the initially highlighted cards are clicked the game is over. What to watch out for: you need to track the cards that were clicked in the grid, you need pick N random cards to be highlighted for each round of the game. You need to make sure the gird of N cards can be increased and reduced. It's not enough that the app works, you also need to write clean/readable code. You have about 40 minutes to implement this, and you need to talk through your work.
Long process. System design felt like I aced it but they didn't pass me. It was the classic design a hotel booking platform question. They put you through a lot of rounds up front.
