I was curious to know, are there any developers (freshers) (esp in India) who use languages like Python/JS in oncampus and offcampus coding rounds/OA?

Have you ever run into runtime/depth/speed issues while giving coding rounds of companies?

[I know that Python works fine in hackerrank and hackerearth coz they respect its slow runtime, but is it true for other platforms like TechGig, Mettl, etc?]
