Experience:

A candidate for a Data Science Internship received a CodeSignal Online Assessment.

The OA primarily focused on general coding problems involving arrays, strings, hash maps, and occasional simple dynamic programming. There were also "light stats or SQL style prompt[s], not heavy ML."

Tips provided for this assessment included practicing 2-3 timed runs in CodeSignal practice, narrating edge cases aloud, keeping solutions tidy, handling null or empty inputs first, and aiming to finish the first two problems quickly to allocate more time for the trickier ones.
