For a job that has a bend for distributed systems, what would you ask the candidate? Easy, intermediate and advanced questions are all welcome. I don't have specific requirements for the job. General questions are fine.
On top of my head I can think of:
Advanced (?)
First I have to say that I'm a computer science student, and haven't got a job yet.
Distributed Systems is a very broad area.
A few things:
Asynchronous vs Syncronous communication Or Blocking vs Non-Blocking communication, what is the difference.
CORBA, RPC, Java RMI, JMS, AMQP - Describe briefly the technologies.
Maybe the most important: CAP Theorem - Consistency, Availability and Tolerance to network Partitions, describe the CAP Theorem and give one example of a system with CA, AP and CP.
Messaging, Message Queues, Message Brokers - You should probably know the characteristics of Messaging, it's often used for integration.
Two Phase commit - very important.
Byzantine Generals problem, also important.
Web Services - both WSDL, and RESTful.
SOA - Service Oriented Architecture, very important to know the characteristics, know the pros and cons.
EJB, Java EE applications servers, .NET WCF
