Primathon interview questions

coding rounds with medium-difficulty problems (like array sorting or matrix transpose) and technical discussions on core concepts (Java, Kotlin, Android, OOPS, React.js), often with pressure, asking for multiple approaches to a single problem, focusing on fundamental skills, and sometimes including puzzles or behavioural aspects about project work and learning culture

They interviewed like a company offering very high package. My interview went for 1.5 hrs. They asked everything as core cs subjects DBMS,OS,CN,DSA,OOPS and after conducting all the technical rounds, in hr round they told me domain i am working is not in their company. I have submitted my resume already, so couldn't they go through it and told me already? Total Time waste, company don't value time of candidates.
