Insanity Group interview questions

Was asked to meet with the in-house recruitment team who scheduled a video call. No one showed up and so I emailed about 10 mins into waiting on the call to reconfirm the meet and ask if all was ok. Waited a further 10 mins, no one showed up. No response. Followed up a day or so later to inform the team of my disappointment of not only being “stood up” for the interview but the apparent lack of consideration for an applicants time. No response.
