FAANG is an acronym for Facebook, Apple, Amazon, Netflix, Google. Those "tech giants" have a complex recruitment process designed to select the best of the best. Around 3 million people applied to Google alone in 2020. Only 20,000 of them were hired, which gives us a 0,67% acceptance rate!
With so many applicants, FAANG companies had to come up with an efficient and accurate hiring process. After years of experimenting, most tech giants decided to conduct phone screening and five 45 minutes to an hour onsite interviews. The phone screening usually takes about an hour, and is easier than an onsite interview. The idea behind it is to avoid wasting time interviewing people who wouldn’t have a chance of passing an onsite screening anyway.
We will focus on describing the technical interview for a software engineering position. The most significant difference between "tech giants" and smaller companies is that they are not so concerned about your knowledge of programming frameworks. Technologies change rapidly. There are new internal frameworks, introduced at FAANG companies, almost every month. An excellent developer is an engineer who can learn and use them almost instantly, and that's what they are looking for in these interviews: fast-learners and intelligent people.
