Extremely snotty attitude, as if as a SIG they're developing something better and more high-tech than Google or any other top software product company, while the interviewer guy holds a simple Bachelors degree in Computer Science from an ordinary (not even Ivy League)!

Absurdness of interviewing process set by HR is in not having higher educated Master's or Ph.D degree holder to interview higher educated candidate. Bachelor's degree holder is interviewing Master's Degree holder of the same field and more experience. If Bachelor's Degree holder is given an opportunity to hire senior guy, why would he bring additional competition for himself? This is absolutely not American exceptionalism! This can be clearly defined as no-value for higher education in company. No other country have such practices in place!

Even if candidate has worked on the same systems with better and bigger firms and he or she has value significant value addition for company but if it's not in interest of the interviewer then his/her resume goes in trash based on misuse of decision making authority of such manipulative interviewer.

A question asked were not part of job description. Array vs List differences, their big O notation and their insert update and delete time at beginning, middle and at end.

Following questions asked were totally irrelevant

1. How the update time at end can be changed?

2. What is faster in C++ and C? What I will select to design new system?

3. Difference between Mutex and Semaphore?

4. What is underneath data structure for Arrays and List? - Is SGI in business of writing and selling STL as a product? Why do an application developer need to know all these. As an application developer, one has to simply know memory and time complexities!

It's like is Civil Engineer is building bridge, asking him composition of brick and mortars! How does it matter? Civil engineer is not in business of making bricks and mortar, he simply care the compressive and tensile strength and settlement time of the mortar. Civil Engineer has nothing to do with mortar making.
