Delhi Private School Dubai interview questions

Applied online. Got a call and had a chat regarding the role and pay, and I was invited for an interview at 8 AM the following week at The Gardens in Dubai. Went for the interview, waited for 1.5 hours and then, was given a task to consolidate an article. Took another 30 minutes for them to arrange a laptop and did not inform prior to carry a laptop . After task completion, had to wait for yet another 2 hours and still was not called for the interview. In the meantime, I was asked to do random tasks like creating a presentation to kill time. When asked HR regarding the delay she said to wait for an indefinite time so I decided to leave. Absolutely terrible interview organization and impolite HR.
