Strung along by HR for 2 and a half months with assurance that a job offer was on the way after the interview. Followed up several times and had positive interactions, then got completely ghosted. It is completely understandable to not end up wanting to hire, but totally unprofessional to not even have the courtesy to send an email and just ghost an applicant. I now have several years in the industry and would never recommend this company to a new engineer.
