Chalkboard (UK) interview questions

Unprofessional and disrespectful of people time I applied via LinkedIn and received an email quickly to schedule an initial chat. When the time of interview come, I showed up 5 mins earlier and waited in the call. Interviewer never show up and no reply on my follow up email. After a week later, I received an email from interviewer default job application unsuccessful email. I don’t recommend this company.
