Lightspeed Software Engineneer interview questions

1. First round was a take away homework for sales and lineItems which I did great, it was with a team different that the 2nd round, and this team was good and asked me good question. 2. Second round was extremely frustrating, I was coupled with a "Senior" Engineer that doesn't know what hes talking about. He asked about how to Architecture design for a "chess" like game. But what Architecture design he did not specific until 15minutes passed and then hes like "oh I want back-end/front-end architecture design", while I was thinking about cloud design. He kept interrupting me during my explanation, and did not guide. I've never had such a bad interviewer like this before.
