IFLY
Trust me I have been in your shoes, I was there in IndiGo for a year and I can tell you that some of the FO's there need to be asked questions; and not technical questions but basic memory items and limitations.
Of course most of the FO's are very good, depending on your attitude they will feel comfortable asking you questions and you two can discuss. When I was there I'd call the FO ahead of time and ask them if they wanted to discuss a topic rather than twiddling our thumbs and most of them were very enthusiastic. I'd let them pick a topic, study/read up and next day or day after discuss it during the flight.
Good luck and you know there is one FO in DEL you should never ask any questions. RS didn't know memory items more than two years ago and I doubt things have improved.
