If you’re looking to hire more quality software engineers faster, then you are probably researching the various online coding interview platforms.

These tools allow recruiting and engineering teams to effectively screen more applicants in an unbiased way that allows for the right candidates with the right skills to get the job.

Additionally, online coding assessments (along with video interviews) have become more popular in the current COVID-19 pandemic where in person interviews are becoming necessary with most offices closed.

Below is our research into this space - everything you need to know before deciding on whether or not to move forward with buying a coding interview solution, along with suggested partners that we’ve personally vetted.  Good luck and let us know if we’re missing anything!

We spend hundreds of hours researching the best HR and recruiting software so you don’t have to.  We never take money from vendors during our research phase and rely heavily on practitioners and experts to help us recommend the right software.  However we may earn a fee if you click on vendor links on this page.
