Duffel carries a Seen Grade of 69/100, with an average wait of about 17 days to hear back and a 28% ghost rate. Here's what applicants report.
London travel-booking API company. Interview experience skews negative (33% positive): candidates describe an unpaid take-home that took hours with promised feedback never arriving even after follow-up, and a Head-of-CS applicant who hit repeated reschedules then a rejection without ever interviewing. Engineering loops rated easier; some staff praise growth. Ghosting and unpaid-assessment friction are the main risks. Glassdoor-based. Reported average time to first response is about 17 days. Applicants report roughly 3 interview round(s).
