American Electric Power (AEP) runs a highly structured hiring loop that leans on standardized pre-employment tests before anyone talks to the candidate. Skilled-craft and operations candidates (lineworkers, plant technicians, system operators, meter servicers, dispatchers, equipment operators) are first funneled through EEI test batteries administered by AEP in partnership with the Edison Electric Institute (CAST for line/mechanical roles, POSS/MASS for plant operations, SO/PD for operators) and/or a HireVue Virtual Job Tryout that is emailed as a 72-hour-expiring link; distribution line workers advancing to the next phase take an additional Journey Level Assessment. Once past the test gate, interviews are typically panels at the Columbus, OH corporate HQ or an operating-company office (Public Service of Oklahoma in Tulsa, AEP Ohio, Indiana Michigan Power in Fort Wayne, etc.) and skew heavily behavioral/STAR (tell me about a time), with corporate/engineering analyst loops occasionally adding a resume-and-project deep dive and an in-person second round with the same first-round panel; nearly no line-work technical grilling is reported for craft roles once the CAST has been passed.

American Electric Power’s official process
AEP's official Pre-Employment Test Prep page names two pre-hire assessment tracks. Track 1 is a suite of EEI (Edison Electric Institute) tests, with practice materials behind an EEI Skillbuilders portal (login 'aep' / password 'aep'), used for Cook Nuclear roles such as Instrument & Controls Technician, Radiation Protection Technician and Utility Operator; the CAST battery in particular gates entry-level Line Mechanic (lineman apprentice) applications. Track 2 is a HireVue Assessment, described as a consistent pre-hire evaluation used for Building Maintenance Technician, Dispatcher, Equipment Operator, Instrument and Controls Technician, Lineworker, Meter Servicer, Plant Technician and System Operator roles; candidates are emailed a link that expires 72 hours after issue and must finish inside that window or drop from consideration. AEP notes that upon advancement to the next interview phase, journey-level distribution line workers take an additional Journey Level Assessment, and offers a downloadable Journey Level Assessment Study Guide.
The candidate spoke by phone directly with the VP of Finance in a single conversational round. The interviewer stayed at a general-interest and resume level rather than probing technical finance skills, and the candidate reports there were effectively no difficult questions; the closest to a difficult one was a fit question about whether they saw themselves working in a utility, given the industry's reputation for being unglamorous. Interview source was an online application and total process length was under a month.

On-site panel with hiring manager plus team happy hourPanel
The candidate interviewed on-site at AEP's Columbus HQ with a hiring manager, then was required to go out to a team happy hour at Champps at Easton (Lennox area) with the whole team as an evaluation step. The commenter recalls the manager was heavily into a specific pop-music band and asked if the candidate liked them; the candidate felt obligated to agree, and describes the overall experience as uncomfortable. They did not get the job and, in hindsight, felt they had dodged a bullet.

Behavioral panelBehavioral
The commenter, who describes AEP's process from the interviewee side and provides insider building/access detail (park at the employee garage north of Spring, sign in with the security guard, HR meets you in the lobby), says AEP interviewers commonly run a behavioral format. Named examples given were tell-me-about-a-time-you-overcame-an-obstacle and tell-me-about-a-time-you-had-a-problem-with-a-teammate, with an expectation that the candidate be honest and self-aware about limits given they are just out of school.

In-person behavioral interview at downtown Tulsa officeBehavioral
Community college freshman interviewed in person at PSO's downtown Tulsa office (6th Street area) for an Electrical Design intern role. Reports the loop was roughly 90 percent behavioral. When asked to walk through a personal project, the panel appeared unfamiliar with the content because the candidate's project was heavily electronics/math oriented rather than power-system design. The candidate was told they would hear back the following week; after six business days with no response they were unsure whether it was a soft rejection.
