How many years' working experience does Amazon, a second-level software engineer?

Amazon, second-level software engineer, 2 to 3 years working experience. SDEII, a secondary software development engineer at Amazon, generally has at least two to three years of industry experience. When I first joined, I was SDEI. For most programmers, working in five technology companies, Facebook, Amazon, Apple, Microsoft and Google, is not out of reach. After passing the online written test of Amazon, I flew to Seattle for an interview. Just a week after flying home, I received a congratulatory phone call. The people on the phone also discussed other issues with me, such as common salary and benefits, and some "extra" contents, such as moving allowance, entry bonus, stock options and so on.
