Coding Technical
The interview was pretty standard and laid out well. It was meant to check out my tech skills and how I solve problems. The questions were clear and to the point, so they could check the main stuff efficiently. All in all, it was a smooth process and not too tough, making it a comfortable and fair experience.

Then, there were 3 technical rounds: one coding question with an easy problem, a systems design question where I had to design a URL shortener, and another coding question about implementing an insert method for a BST.

Technical Coding System Design
I had two algorithm interviews, one where I had to use a hashmap and another with a binary tree problem. Then a third interview was about system design, specifically a URL shortener. The interviewers were Chilean software engineers and had a really rude attitude, like they were doing me a favor. It was obvious they'd reject me from the first interview. Makes me doubt the company has a good environment, despite what some engineers say.
Confirmed questions3 questions
- Solve an algorithm problem using a hashmap.
- Describe how to insert a node in a graph.
- Design a URL shortener.
