ITONICS interview questions

You get a call from the HR lady then a take home assessment in node then a technical interview where they ask you about JavaScript i feel they wasted my time i expressed from day one from the initial interview that am in Joburg and moving to cape town isn't an option for me they still went ahead with the interviews only to reject me at the last stage due to my location which i find very unfair if my location was bad for them why waste my time todo the home assessment and the technical interview the last interview was supposed to be 3 people only one showed up that gave me a sign that things are not going to end well for me but the interview was easy i would have appreciated it they rejected me after the first interview when i mentioned my location instead of putting my hopes high and wasting my time doing the tech assessment and technical interview while they know that am not their candidate
