"You may not struggle with office work and may do fine interacting in person, but that’s not true for a lot of people."
I have people who do far better at home than in the office, and some on the other end of the spectrum. People come in all sorts of shapes and sizes and finding the right people is the same challenge regardless.
What is hard is tooling and setting up processes that work for remote people. The world is at the start of figuring that out at scale and there is lots to learn. But hiring is always going to be the same game, finding the right people for the role and its requirements.
If I were hiring for an oil rigger it would not be more complex than hiring for a great developer. It will definitely be different, but all recruitment is different and sees different challenges. But it's always going to be about knowing what to ask, knowing your industry, and doing your very best to find a process that selects fairly and efficiently. Remote work hiring is just a different challenge that we are all just getting used to. People are hard problems to solve.
