Senior Software Engineer Interview Experience - Seattle, Washington
Process
The process was good and well organized. The HR kept in touch throughout the interview.
However, after the interview, they did not have the courtesy to let me know their decision. This is something I always find very insulting, as I invested time and had to take a day off for the interview.

- 3.0Good Benefits, Long HoursSenior Software Engineer • Former EmployeeSeattle, Washington, United StatesFebruary 6, 2017Pros: Great benefits, job security, and you have the ability to work in other cities as it is a large company.Cons: Long hours, as it is a global company. Meetings have to be scheduled so all attendees from several countries can make it. This forces you to take 5 a.m. or 6 p.m. meetings a couple times a week. Projects take much longer to complete due to developers working across different countries. It also takes a lot longer to complete projects due to needing approval from the New York office technology department before proceeding with each step of development.
