Preparing for a Software Engineer Role at Speechify? Here's What to Expect in the First Round

If you've applied for a Software Engineer position at Speechify and have been invited to take their online assessment, this post will give you a clear idea of what to expect.

The first round involves solving a coding challenge hosted on a private GitHub repository. Once you're granted access, you'll have 90 minutes to complete the task. After the time limit, your access to the repository is automatically revoked.

Below is the problem statement from the assessment:
