It's not just the interviewing, there's a huge amount of friction / switching costs for changing jobs. * Applying / ATS forms * Phone calls with recruiters * Doing screening tests * Interviewing * Background checks * Drug testing * Onboarding, training, getting to know people, learning the codebase and systems * Moving 401k, stock plan stuff, vesting * Choosing health insurance, switching providers, etc ... If you add it all up, the time from feeling "Hmm, this job isn't the best, maybe I should apply for something else" to being comfortable in your new job instead of "the new guy" is something in the order of 6-12 months; less for new junior jobs, more for senior roles. Once you appreciate this, it's absolutely not something to embark upon any more often than necessary.
