RelayHealth Senior Software Engineer interview questions

Got a call from recruiter, spoke about my experience and position requirements, after answering 20 true or false interview questions in c#, asp.net, sql server then he submitted my resume to hiring manager. Questions were basic like bool vs Boolean, size of decimal data type, ViewState etc.. Two days later got a call back for technical phone interview, it involved few more technical questions in C#, like about CLR, yield statement, extension methods, IEnumerable interface, Caching, State management, and interviewer asked me to write a small method that takes an integer number as parameter and returns sum of odd digits in the number and asked me to read out the statements.
