I sense the dire need for separate interviewing processes for anything that involves CRUD/WebApps with a database/Front End etc. and anything that is math/compute heavy. Although I feel it is correct on the interviewer's part to expect me to know what these algorithms are and their general behaviour, expecting me to have it memorised to be considered eligible for writing CRUD apps and struggling with build tools and outdated test infrastructures is just infuriating.
