Meditab Software Angular Developer interview questions

It started with the introduction and then DSA questions were asked. The questions were not that difficult, I was able to solve them within the given timeframe but yes I did code using Python whereas the interviewer expected JavaScript. Two questions were asked, One was related to prime numbers and the second one was based on GCD. The interviewer wanted the code to be in JS only. I was asked to explain the time complexity of the code.
