I applied online. The process took 3 weeks. I interviewed at Cresta (CA) (New York, NY) in Dec 2025
Interview
First is the online assessment via Coderpad- 3 coding questions in 45 minutes, Second is a 15-minute interview talking about background, Then a one-hour technical interview with a software engineer.
Interview questions [1]
Question 1
A dataset which contains examples labeled with different classes• (single label, multiple classes), for example an animal image classification dataset containing different types of animals, one animal per image.
You want to randomly sample an n-element subset from this dataset in such a way that the classes are as balanced as possible (least difference between the number of examples sampled from each class).
Write a function which given n and the number of examples in each class, computes how many examples should be sampled from each class.
OA 3 leetcode style- one with python file traversal.
Recruiter screening
Practical interview- email say it won't be LC but it is exactly a LC modified problem with a twist of OOP. I can even find that LC number online. Don't believe what they say in the email.

Question 1
All problems are fair if you practiced LC Easy and Med problems. Brush up your OOP for Practical Interview.
