InvestEngine interview questions

Got invited to the final stage and was asked to present a task. I was chased to complete it and send it over to them ahead of time. When it came to the final interview, there was no mention of the task and 0 recognition or thank you for my time. It was an extensive presentation on CRM strategy and took me hours. It has been a month and 0 feedback provided. Very unethical and unprofessional.

Stage 1) Had interview with HR called Enrique. He didn't turn up to the first meeting, 5 hours later called to reschedule. Did it the next day and he was 15 mins late again Completed their gamification quiz around 40 mins 2nd stage - met with Hiring Manager, all good there It's been 3 weeks, no response from HR after an email, realised I have probably been rejected as the option to log into candidate profile was not available anymore. Perhaps a rubbish HR or signal of the type of company
