Liftoff Full Stack Web Engineer interview questions

They contacted me to see if I'd like to interview. They sent a link where I could select times for a phone screen. But then they didn't send a confirmation, and I didn't hear for them for a month, after the selected time had passed. I'm not sure why they used Hangouts for the call. If it's audio only anyway, just use a phone. I'm not sure what they were using with Hangouts, but the audio was horrible. The interviewer told me he liked my answers to the soft skill questions, and that I wrote out his preferred solution for the coding problem. But, it was really odd when I'm talking throughout the problem, and the interviewer wasn't saying anything. It seemed like he decided to go back to work for a while. And the coding problem wasn't anything practical or useful, it basically just tested if I could use for loops. I was happy to get off this call and stop wasting my time.
