I applied through a staffing agency. The process took 1+ week. I interviewed at Dealogic (London, England) in Feb 2014
Interview
First stage was a phone interview with typical questions for this stage (OOP, SOLID, Design Patterns, bit of C# and SQL) with two developers. After that competency based face to face stage including a short coding/logic test on paper again with two developers. Offered the job the next day after the f2f interview.
Interview questions [3]
Question 1
C#: DateTime.Parse, what is this, what should we ensure calling it?
