Dexcom Applications Engineer interview questions

First contacted by recruiter. Quick 30 min chat regarding past work experience and how they can rewrite my resume. Very condescending. Get passed off to 2 other recruiters/hiring managers. Confusing process. Interviewer sounded like they were interviewing from car. Code challenge sent to email to complete on a weekend - 48 hours due date. By this point, exhausted from the whole process and confused of who I am even dealing with. Then boom...Covid 19...dead silence. Email 3 weeks later that another candidate has been found. Overall bad experience and seemingly unprofessional and disorganized. Probably about 7 or 8 hours of time spent coordinating interviews between schedule and working on code challenge. Wouldn’t accept position here in future just based on interview experience.
