The interview process was lengthy and disorganized. You could go weeks without hearing from Next Street (even when you wrote to them asking about your status) only to randomly get an email congratulating you on moving forward to the next round. You are only really allowed to chat with Noelani via email and are discouraged from reaching out directly to anyone else on the team, even folks you previously chatted with.
I accepted another offer before Next Street even reached the final stage of their interview. I went through a 3 interview process between interview 2 and 3 in Next Street's process.
It was mostly talking with people at the organization-- hiring manager, HR, a coworker. The people are lovely and passionate about their work. I think this company is probably amazing, but their hiring process is deeply broken.
