MobileLIVE Front End Developer interview questions

I first got a phone call from their HR and then proceeded to a video call. On the day of the video call interview. No one showed up on my screen. I've been waiting for 30 mins to join the video conference. They never showed up. I had to email and HR to let her know what happened. She said she will look into it but never bothered to reply. I got another email from them from Hiring Manager for a Senior Position. I asked if they have a Junior Position available and we tried to set up a phone call interview. I responded to tell him about my free time and I never got a response back or a phone call. Be careful applying to this company. They might waste your time and forget about your interviews.
