Very unprofessional
First of all, they don't respect your time and show up late for the interview without even apologizing for it.
I was given a take home project which I did in Firebase and Node. They didn't seem interested in my solution or even willing to relate it to what they do.
All I heard were bold and naive statements about technology from their CTO. The guy didn't seem to know a thing about software development.
In the end, I was not offered the job but I got the feeling they were not serious at all in their hiring and they didn't know what they want to do with their product.
I read some of the reviews that people gave about this company. It seems like a toxic and unhealthy place to work for. Honestly, I am not surprised and I am glad I didn't get an offer from them.
