Hello, Thank you for your interest in Nisum and taking the time to provide feedback. We take all input very seriously here at Nisum, and would like to take this opportunity to help clarify the situation you've referenced. As we discussed and was conveyed to you, Nisum (like many other firms looking for excellent talent) believes in offering the best offer to a candidate after a thorough technical and behavioral assessment. After our evaluation, we found that there was misalignment in expectations between parties. Your expectations seemed to be based on hearsay about working on the west coast. There was also an apparent mismatch between your current views as a contractor versus joining as a full time employee. Finally, we did not say that "you are eligible for less salary." A formal offer was never extended as we could not meet each other's expectations. We apologize if you believe that the interview process was not as you'd hoped. Again, thank you for your interest in Nisum Technologies! Wishing you the best! Nisum HR Less

The OOPS Concepts and Interface questions are pretty simple to answer. For the CSV file, a quick and dirty solution would be to use a file reader to read the file line by line, split on the comma and print out index 1 of the list resulting from the split. (index starts at 0) Easiest alternative to Java is python, which is pretty much exactly the same method. This is by no means the most efficient implementation Less
