The whole phone interview process was pretty straightforward.

I was asked to solve some algorithm questions, using my preferred coding language.

The key points for a successful coding interview are:

• Setting up very clear objectives before real work.
• Understanding what the question means.
• Clarifying the meanings of concepts mentioned in the question.
• Determining which data structure or algorithm to use.
• Ensuring the solution can compute the expected outcome.
