Consist of 3 technical rounds - difficult level was okk and mostly depends on practical questions and deep knowledge of js and react.
And 1 managerial round which might also turn into tech one
The process took 1 week. I interviewed at SmartBear in June 2011
Interview
Had a 30min phone interview followed by an 1.5hr on-site interview in the next week. Phone interview asked questions about data structure and code-writing in google doc. The on-site interview were typical questions about Linked List. Wrote code on white board and for each question, they ask the special cases and how to test it.
