Research has found that job vacancies increased in the weeks running up to the original Brexit date of March 29.
Vacancies and salaries for new jobs were both up by just over 3 per cent in March compared with a year ago, said jobs site CV-Library.
The biggest increase in vacancies were in Edinburgh (up by 16 per cent), Bristol, Portsmouth and Cardiff (all 9 per cent), the study indicated.
Edinburgh also witnessed the biggest increase in advertised pay at 15 per cent, said CV-Library.
Chief executive Lee Biggins said: "The latest findings are a testament to the resilience of the UK job market.
"In response to the uncertainty surrounding the outcome of Brexit, employers increased their hiring efforts by pushing up salaries. There is no sign of this trend stopping.”
The UK was originally set to leave the European Union on March 29, but the prime minister extended the deadline after failing to gain support for her withdrawal agreement.
