It sounds like you had a smooth interview process! Getting the job within two weeks with just one interview definitely speaks to your qualifications. It's true, the hiring process can vary widely depending on the company's culture and procedures. Congratulations on landing the job!

I applied online,the process took whole day,they offered lunch and reimbursed transport fee for all candidates. 1.Phone screen,introduce your basic situation,if you know the position in general. 2.Some paper work,then face to face interview with technical manager. 3.Group interview,a team cooperation,build a zoo or something.
