Will companies ask me to solve their coding problem as well

Most of the companies on Geektrust will not ask you to solve one more coding challenge. If they do, it is mostly to test for an aspect which has not been covered in the regular Geektrust challenge. For example a company may want to test your API design and architecture skills and will have you solve a challenge specific to that.

However there are some companies which, for the sake of consistency in their process, ask all candidates to solve their company specific coding challenge. We actively discourage this, and are always talking to companies to get rid of the coding test from their process.
