first priority:
you must very familiar with the project you have involved . describe the merchant purpose of the product , draw the high level architect diagram , class diagram and sequence diagram .maybe state diagram is preferred choice for showing your multi-threaded experience. further give the deep knowledge about the lower layer and kernel struct and their communication diagram .
second issue:
you must prepare for the each detail knowledge of you masted area and tech you mentioned in resume , the interviewer may ask only one small question for your proficient area or theory in order to testify your resume reliability.
third issue :
good english expression about question related in your experience , your reason for leaving last company , your most tough task during work , your most achievement during work , the most valuable bug you have fixed and so on.
last but not easy for me :
last step is to negotiate with the HR about the salary . if you really want this job in this company ,don't care about the really pay , tell HR " what i needed most is working for the company ,contribute for the company and grow with the company , salary is not the first priority. " you can image that when you leave this famous company , your experience is a competitive edge for bargaining. i have made a mistake with an HR in a famous company. A fall into a pit , a gain in your wit!
sincerely wish you guy to succeed .why i write this ? to remind me what is the most important ? a good pay just for now or a lower pay for a good prospect in future ?
