I was shortlisted from campus selection process for an onsite interview. Even though I was finally rejected, I personally feel that interviewers were not that skilled or maybe my particular interviewer was feeling sleepy! He asked me an sql query for a given situation and I said I am not confidant in sql. To this he said in a frustrated tone that I have an Oracle certification, then how can I refuse to write an Oracle SQL query? I felt bad, not about myself but about his limited ability to read things in a CV. In the certifications section he saw Oracle word somewhere and assumed that it is an Oracle SQL certification. Java was clearly mentioned there but he choose to ignore that. Anyway, I explained him what an Oracle Certification is and you can have it in different domains like java, sql, cloud etc. Rest of the interview went normal with oops concepts, a coding question and a situational decision making problem at the end. I expected him to dig deep into data structures and algorithms but he couldn't ask anything beyond simple linked list and there wasn't even a single algorithm question even though I told him thrice that I love algorithms!!
