• They don't have a standard interview timeline • High probability of being ghosted after the interview (even if you send a follow-up email to the recruiter/HR, they will not respond unless they are sure of you) • Some interviewer doesn't sell their company to you and most likely make you feel the need to impress them to get the job (yup, they will make you feel that you need the job more than they need you) P.S. Their HR/Recruiter/Interviewer would best reflect the values and work ethics of the company, even from the email/text messages be aware of how they communicate (e.g. tone, message structure, and timing). Trust your gut instinct.
