"The last two years has been great for job opportunities because of remote work meaning you don't have to isolate a job search to your local area. So that's seen the scramble for talent be very competitive and wages have gone up really high."
"What we're seeing now is a contraction in budgets and staffing."
He said some technology firms companies, including Amazon, are likely to be hit particularly hard.
"Amazon is very, very bloated. So there's lots of people there but they're not providing a lot of value so they're first on the chopping block."
