Qamar Mohammed Malik claims Amec Group Limited ignored his CV in November of last year purely because of his foreign name.
Mr Malik said Lyne Bowen, the Amec office manager in Treforest, south Wales, indicated they could find him work given his experience when he telephoned her before sending his CV for the first time.
After emailing his CV to Amec, Mr Malik was told by Ms Bowen on November 8 that the company had already seen his CV when it was forwarded to them by the AndersElite agency and they had no suitable vacancies.
Unhappy with his rejection, the 49-year-old, from Cardiff, decided to compose a similar CV, but with inferior qualifications, under the name of Rhyddir Aled Lloyd-Hilbert.
On the false CV, "Mr Lloyd-Hilbert" had an almost identical employment history but had fewer O-levels, no CSEs, and was slightly older than Mr Malik.
Mr Malik said the Treforest office of Amec responded "positively" to this application within three hours of it being emailed to them on November 20 - less than a fortnight after being rejected under his real name.
The tribunal heard Ms Bowen emailed "Mr Lloyd-Hilbert" a job description for a Quality Inspector and after interest was confirmed in this role, a maximum salary of £33,000 was indicated.
The construction arm of the Amec Group, who were bought by Morgan Est in July, deny racial discrimination.
