Interview
It was very bias. There are a couple of GenZ kids, and they are assessing you very subjectively. Even if you solve the coding questions correctly, they are proposing some stuff to eliminate you.

Question 1
Reading a txt or csv file and organizing data frames accordingly.
Take home and then call with a ML engineer for second round. The take home took quite a while to do but was straightforward. I was nervous for the main one so didn't pass.
I applied online. The process took 4 weeks. I interviewed at Scale
Interview
Applied online. Fist interview was a live coding interview session, dealing with raw data for CV task.
I thought the interview was super easy even though I am more proficient in NLP than CV. I completed everything except for the very last task, for which I didn't have time to finish coding.
I didn't pass.
