FAQs for Job Seekers
Since Westside Personnel partners with a range of manufacturers — from small shops in Pacific to large plants in Fenton — it’s helpful to ask about the specific industries involved (e.g., automotive parts, HVAC units, consumer goods). Knowing what you’ll be assembling helps ensure your past experience aligns with the role.
If you’re new to the field or looking to upskill, ask about job openings where on-the-job training is offered. Westside often works with clients who are willing to train the right candidate, especially if you bring good attendance and a strong work ethic.
Since shift flexibility and job stability can vary by client, it’s smart to ask about day vs. night shifts, overtime expectations, and whether the role is temporary-to-hire, long-term contract, or seasonal. Westside Personnel can help match you with a schedule that fits your lifestyle.
As Westside works with both large manufacturers and small shops, environments can differ. Ask what kind of personal protective equipment is provided, whether safety training is conducted, and how the employer handles quality control — especially if you’ll be using hand tools or operating machinery.
Westside often helps job seekers find not just “a job” but a career path. Ask if the company offers promotion opportunities into lead roles, QA, or machine operator roles, and whether past placements have been hired full-time or moved up internally.
