Okta Fullstack Developer interview questions

I was invited to an interview at Okta-Spectra in Tel Aviv and asked to come to their office. I live 1.5 hours away from the office. One hour before my arrival, I received a phone call informing me that they had already hired a candidate. I had taken a day off from work and was already halfway there. Do NOT interview with this company! They could have informed me in the morning that the interview was canceled or, alternatively, conducted it over Zoom. Furthermore, they should have stopped interviewing once they had a candidate who had already signed a contract. This company has no respect for candidates' time or basic dignity. Avoid them!
