I'm going a different route with interviews and wonder if anyone has input... I'm a senior backend dev with 10+ years of experience. Breadth of projects, masters in CS, open source work, team lead, top contributor, great references, etc. But I cant pass a coding interview, because I kinda freeze up during algorithm whiteboarding questions. I get requests for interviews daily and have been considering starting with a cover letter that basically says I'm not good at coding interviews, but love to talk tech (and see other positives above). Could I do a homework assignment or anything else to show my worth? Has anyone had any luck with an approach like this?
