Hi All, I got an OA invite for the above-mentioned position in CodeSignal. This is my first AI Engineer OA, and I don't want to screw up. All the info regarding this is outdated. The assessment mentions testing the following * Basic Coding * Data Manipulation * Implementation Efficiency * Problem-Solving If anyone has taken the test, kindly reply. 1. What type of questions? What modules are there? They mentioned data manipulation, but I am not sure if pandas is allowed. 2. How tough is it, and any recommendations to prepare for anything? Thank you!.
