Derby-based train maker Bombardier has said about 1,200 people attended its jobs fair at Pride Park.
The company said 360 people came through the doors in the first 45 minutes. Bombardier described some of the applicants at Saturday's event as "outstanding".
The firm held the jobs fair in a bid to fill about 400 short-term vacancies.
Before the event, Bombardier said the roles could appeal to people made redundant by JCB and Toyota.
A spokesman said: "Some of the quality was outstanding and we feel confident we will be able to fill the majority of the roles we have.
"A number of key projects are coming to a head in the coming months and the extra staff are needed at the three Derby sites."
Staffordshire-based JCB laid off 2,000 workers during the recession, while Toyota has started a voluntary release programme in a bid to trim its workforce by about 750.
Bombardier makes trains for London Underground and other operators.
