The initial recruiter call includes standard questions about my work experience and what I am looking for in my next role. I was puzzled when the recruiter mentioned that I did not have enterprise software experience (which I did, but with a different vendor than what they were looking for) and was skeptical that I fit the job position. Anyway, they decided to move forward with the technical phone interview. The technical phone interview was rather unpleasant. The interviewer called in 5 minutes late. We also experienced technical difficulty setting up the collaborative coding tool. After a few minutes resolving this issue, I finally got the chance to type in my solution. I explained my approach and provided examples to test my code. The code ran fine with my test cases. However, the interviewer seemed dissatisfied with my solution, saying it was wrong, but was unable to point out why my logic was wrong nor provide counter-examples to fail my code. Time ran out, and I was left with the conclusion that they would not move forward with the process, and the impression that the interviewer was not knowledgable about the interview question he's asking.
