Software Engineer Interview Process and Questions

Redirects to legacy blog post. A short time ago, I was tasked with finding the right software engineer/s for the organisation I was working for. I settled on a process, a set of background questions, a set of practical programming exercises and a set of verbal questions. Later on I cut the set of verbal questions down to a quicker set. In this post, I’ll be going over the process and the full set of verbal questions. In a subsequent post I’ll go over the quicker set.

The messages that are transferred between clients/services can be intercepted and operations performed on them.

This can be usefull for load testing, concurrency testing scenarios amongst others.

Duplex communication and callbacks in WCF

Redirects to legacy blog post. I was reading in the book Enterprise Integration Patterns that my dev manager bought for the team, on the Message Endpoint pattern on the way home from work a few days ago. “A Message Endpoint can be used to send messages or receive them, but one instance does not do both” From my experience, this wasn’t necessarily true. So I decided to confirm my suspicion. The following is a mix of what I read and tested out.

Built-in MSMQ Bindings

Redirects to legacy blog post. `NetMsmqBinding` only works if you have WCF on both sides of the Queue-to-Queue transfer. `MsmqIntegrationBinding` is targeted toward existing MSMQ applications that use COM, native C++ APIs or the types defined in the `System.Messaging` namespace (as stated by MSDN).
