Presentation Behavioral

It was an online interview that consisted of a 1-hour seminar presentation followed by a panel interview. I'd say that preparing using the STAR method was quite helpful for the panel part. It wasn't overly difficult. After the seminar, attendees asked me questions about my research as curious audience members. Each person on the panel asked me at least two questions. Afterwards, they gave me the opportunity to ask them questions. They were really welcoming.

Behavioral Technical

I applied to a general Electrical Engineering job posting and then had a quick chat with a recruiter who suggested I look into a Fuel Cell Engineer role instead. Following that, I had a 1-hour video call on Teams with the hiring manager. It was a nice conversation, but then I heard nothing back, even after I followed up a few times.

Behavioral Technical Presentation

So at Oak Ridge National Laboratory (ORNL), the interview is pretty in-depth, looking for smart people who can solve problems and are into what we do. It can change a bit based on the job, but generally it goes like this: You apply on our site, sending in your resume, a cover letter, and maybe some project stuff. Then, HR checks if you fit the basic requirements, and the technical folks look at your skills. After that, there's a first chat, usually phone or video, where we talk about your background, why you want to work here, and check your knowledge. This is with HR or the team. Finally, there are panel interviews, either online or in person. We dive into your technical skills with problems and past projects, ask behavioral questions using STAR to see how you handle things, and talk about teamwork because we work across different fields a lot.

Behavioral Presentation

I was reached out to by a recruiter about a Postdoc role at ORNL and applied in December 2023. In January 2024, I was invited for a virtual interview in February 2024. The interview process included multiple one-on-one meetings with future colleagues, a 40-minute presentation focusing on my dissertation and current research, and a lengthy panel interview lasting about 5 hours with two short breaks. The people I met were all friendly and engaging. I received an informal job offer four days after the interview, with the formal offer following seven days later. I decided not to accept the offer due to the salary of around $72,000/year, which was not sufficient for my current life circumstances. I noted that ORNL states 80% of their postdocs earn over $75,000/year, and Glassdoor reports a median salary of $85,000/year for this role. I inquired about a higher salary but was told the offer was the best they could make given my qualifications (Ph.D. in Environmental Science, one year postdoc, two years technician). It seems the pay discrepancy might be related to the specific scientific field, which I believe contributes to inequalities in the scientific community.
