The interview process consisted of several rounds, including:

• An online technical test
• An interview with a senior developer
• An interview with the prospective team

Initially, they were very helpful and accommodating. This included being matched with a buddy whom you could email with questions about the job and the company. After the final round, however, there was a lot of delay from their end (waiting more than three weeks). They promised feedback, but I never received any, which left a bad taste after investing a lot of time in the process.

Discuss a project you have undertaken and technical challenges you've faced.
