Hello and thank you for your feedback! Navdy is a startup on the verge of shipping our first product and, currently, we do not use an automated service to evaluate coding exercises. Each submission is reviewed manually by our CPO or a senior member of technical staff. That said, we truly appreciate the time and effort you spent to submit the coding exercise and apologize for the delay in communication. Sharing your feedback is immensely helpful in helping us improve our process to avoid similar candidate experiences in the future. If you have any further feedback or questions please reach out directly to alisa.grange@navdy.com. Thank you again!
