[PragmaticPulp]

The company isn't going to drag someone through 4 separate interviews if they're not serious about hiring.

One of the reasons it's staggered is so the company or the candidate can end it early if it's not a good fit. Less time wasted this way.

Frankly, I'm kind of shocked by the resistance HN has to spending a couple hours interviewing with a company. You're going to spend several years of your life working with this company. Is it really a dealbreaker if they ask their candidates (included your future coworkers) to participate in a few extra hours of discussion and confirmation?

In the real world, I offer to schedule interviews on lunch breaks, before or after work, or on weekends if that works better for people. Practically speaking, most developers (especially WFH/remote) have zero problems finding time during the day for a 1-2 interview session. That's equivalent a long lunch break or a quick errand.

In practice, I've never had anyone decline an interview for lack of time and very few people ever take me up on my offer for flexible interview hours of their choosing. Most people are eager to get to talk to the company, hear about the job, and show the company what they can do.
