To give you the impression of how big the company is you will talk to multiple people along the way. You'll talk to the recruiter who sets you up with a scheduler who will schedule your interview times with the technical interviewer etc... This is an HR trick to just give you an idea of how big the company is.
Step 1: The "get to know you" call. This is a friendly person who will describe what the position is, what Avanade is and what the company is like. This is the "get to know you and make sure you speak English and are not insane" portion.
Step 2: Technical phone interview. This is an hour long call between you and a consultant who is probably on the bench. Some questions they will ask:
1. What is polymorphism?
2. What is multi threading?
3. Describe ACID as it relates to databases.
4. Why would you use a StringBuilder?
5. What is a SQL Adapter? Data Reader? Dataset?
6. What is encapsulation?
7. Describe the software development life cycle.
8. What is recursion?
If you've been programming for a while, in .NET you should have no problem with this portion.
After I aced this interview, I was told which salary range I fit into. At this point I declined to go further since the salary range wasn't high enough. However, I went through this process two years ago. So I know how the next steps go.
Step 3: In person technical interview. You are basically asked about your experience, to describe what you did on a project etc... You are then handed a marker and asked to code on the white board. Two years ago, the questions I were asked were:
1. Reverse a string and don't use Array.Reverse.
2. Join three tables in SQL
3. Write a recursive function.
After this interview you proceed to the "personality" interview. Basically the hiring manager will meet with you, discuss your background and basically gauge weather or not you'd be a good fit.
