Himalaya Exchange interview questions

I had a warm conversation with HR who was amazing and really enjoyed the atmosphere and friendliness of them. But as for the technical interview it was horrible. I met one guy in the meeting, they are hiring for Golang Developers but they asked 0 questions about Golang. The coding challenge was to implement Knapsack algorithm in Golang, which you can implement in any language, plus I believe it has nothing to do with measuring a programmer's skills, I could have used ChatGPT to answer the question. Also the technical interviewer was cold and not friendly. Wasn't able to properly share a link, and used a broken website to draw shapes, which he gave up drawing at the end because it wasn't visible for me.
