IRIS Business Services interview questions

Interview round was good basic questions were asked.Project written in resume was asked in detail,all about tech stack used and tools used,basic aptitude question to test aptitude skills and 1-2 dsa questions of medium level were asked

They asked only one question. Also did not care to pay attention on what i answer. They asked about abstraction. Prepare oops concepts. Overall if they are not interested in hiring they do not ask many questions. After shortlisting candidates they reject them with no reason. So our whole college drive was an unsuccessful even.
