I applied online. The process took 4 months. I interviewed at Pinterest in May 2025
Interview
I interviewed for a software engineer role at Pinterest. The process started with a 90 minute OA that included two algorithm questions at a medium to hard level. After that, I had a technical phone interview with one engineer, which involved one coding problem and some follow-up questions on edge cases and complexity.
For prepare, I mainly used LeetCode and NeetCode for general practice, and Hack2Hire was especially helpful since the OA format was quite similar.
Overall, the process was structured and fair, and having a solid prep routine made a big difference.
Interview questions [1]
Question 1
One of the main questions during the technical phone screen was to solve a coding problem involving arrays and apply an efficient algorithm. After implementing a working solution, I was asked to discuss potential edge cases and explain the time and space complexity of my approach.
1st round technical phone screening with in 1 hour.
One follow up question was asked.
The problem was not too hard, but it requires you finish really fast without bugs.

Question 1
Leetcode 1564. Put Boxes Into the Warehouse I.
Follow up: what is maximum total box sizes.
Good experience not the best outcome. Was 1000% sure I completed all coding and sys design but was told didn't get enough signal for the competency round. Overall very organized but not very satisfied with the response.
Horrible, el entrevistador ni entendia el ejercicio y queria que lo hiciera a su manera. Tardamos 30 minutos en entender el ejercicio porque el ni lo entendia. Pude hacerlo a mi entendimiento, entonces cada cosa que hacia no me cuestionaba, literal me decia que estaba incorrecto
