ING Senior Software Engineer interview questions

I applied to the job from the company's website and they called me back. The overall process was super, very fast. Interview was good and I got hired after that.

Interview consisted of 4 steps: 1) Online technical interview with 2 software engineers 2) Online personal interview with hiring manager 3) Face-to-face technical interview with 2 software engineers 4) Face-to-face technical interview with hiring manager They don't ask hard algorithms, but expect you to have broad computer science knowledge. Expect to be asked about: Cryptography (symmetric and asymmetric algorithms, prime numbers) Networking Data structures (how HashMap is implemented) Java Generics (extends, super, wildcard) Databases (how indexes work)
