Hubtel UX Engineer interview questions

I got an invitation email: Are you available to meet with us at our office in Komlemle tomorrow Thursday 29th July 2021 at 12:00 pm? I answered yes, because the date and the time was okay for me (the time was the most important). I got there around 11:50 AM, I waited at the reception with other two (2) others guys, after waiting for almost one (1) hour and half a man came in and called an name, one of the guy got up and went for the interview after he was done, the man came and called another name, the other guy went in and it was left only me at the reception meanwhile my interview was supposed to start at 12:00 PM, after the guy was done, i was still waiting at the reception, then the man came and asked me if he could help me, (PS: You will notice that the man did not call my name as he was doing for other candidates) so i gave him my name and he asked me what i was here for, I told him I'm here for the job interview for the UX Engineer position, he asked me to follow him that's when the interview started and it was almost 3:00 PM. But looking at the time i was already disappointed, all I wanted was to finish the interview ASAP because I did not like the how it started. On top of this they don't send you an email to inform you about the current situation of your application. Aside from this horrible experience Hubtel is one of the company i really like, I mean i like the vision and how they are transforming things in Africa, I like their products, I'm even a customer there, i use their SMS API on my personal projects and on some of my clients (Freelance).
