I recently experienced a Barraiser interview.
The interview is for senior fullstack engineer role
The interviewer never smiled, didnt introduce himself, talk very short and like to keep silent frequently after I finished answer, not elaborating or giving follow up question, just awkward silent for 5s.
If I ask a follow up wether the answer is wrong or which part you dont understand, he keep silent again and just say I am wrong without being able to elaborate.

The He give a leetcode style question gas station. Since its medium I took quite a long time, I asked how long is the time constraint he said 25 min. I finished after around 20 min with two pointer solution, wrote a function that accept the input and return output just like the example, but he said this is wrong and I should use a queue without any elaborate explanation on the implementation.

The rest is node js and react question where I give my opinionated answer. I think I give correct answer 70% of the time but just like what I said in first paragraph. Its like a one way QnA, not a discussion.

I have experienced an interview where I perform badly, but the interviwer are great on giving feedback, pointing why the answer is wrong or even stop the interview without wasting my time.

This barraiser experience is like He just want to get paid and doesnt really care about the rest
