The Waterville Public Library is holding a job fair Wednesday, April 27, and in preparation is offering those seeking jobs a workshop on how to get the best out of a job fair.

The job fair is one of two the library regularly holds during the year, said Tammy Rabineau, associate director at the library.

She said the purpose of the fairs — another one is held in September — is to provide local job seekers and businesses that are hiring with a means to connect.

“We have people in the Waterville area who are either unemployed or underemployed and others who are interested in progressing on their career path,” she said Monday. “Many folks are not aware of the employment possibilities in the region. There are many employers in the area with unmet workforce needs.”

Dana Hamilton of Kennebec Valley Community Action Program will present a workshop which will offer advice on preparing for the job fair, including what to wear, bring, ask and how to make a lasting impression, according to library officials.

The workshop is 10:30 a.m. to noon Wednesday in the Colby Room at the library.

The job fair is from 3 to 5 p.m., Wednesday, April 27, and will feature more than 30 hiring employers, these among them:

The United States Army and Army Reserves; Maine-ly Elder Care; Maine Staffing Group; Eastern Maine Healthcare Systems; Mount St. Joseph Residence & Rehabilitation; MCD Communities; Northeast Laboratory Services; Bonney Staffing; Disability Determination Services; Maine Army National Guard; ESM INC.; Waterville, Skowhegan, and Fairfield Adult Education; Manpower; Community Health and Counseling Services; Augusta Career Center; Rodan + Fields; Duratherm Window Corporation; NRF Distributors, Inc.; T-Mobile; On Process Technology; Maine Conservation Corps; Pathways; Johnny’s Selected Seeds; Spurwink Services; Goodwill Industries NNE; Transworld Systems, Inc.; Prudential Financial; Assistance Plus; Maine Department of Transportation; Modern Woodmen; Great Falls Marketing; GameStop; Securitas USA and Kennebec County Sheriff’s Office.

The job fair is presented by the Waterville Public Library, Kennebec Valley Community Action Program, Maine Department of Labor Augusta CareerCenter, Central Maine Growth Council and the Mid-Maine Chamber of Commerce.
