 Employee Stories


Electrical engineer (32) / 4 years at ENI

For nearly four years, I have been conducting design work while being involved in about 15 projects. Having been involved in numerous domestic and international plant designs, I had gained enough confidence and wanted to challenge, especially in the field of developing renewable energy. I expressed this desire to my sales agent, and within two days, my boss sent me a related information magazine in the field and told me to “first, read this and study it”.

Mechanical engineer (29) / 2 years at ENI

Looking back, I have experienced a lot during these past years. I was assigned to the site for about a year, where I experienced construction management and test runs. In addition to designing, I was able to take on new challenges such as verification work for manufacturing test and work as a field engineer. I moved back to the head office, so that I could further improve my skills and currently working on creating drawings and doing estimation work.


An interview with our President/COO, Keiji Hara, was published in the October 10 issue of ENN (Engineering Network / Heavy Chemical Industry Communications). The article is reprinted and translated below with the permission of ENN.

We believe reliable employees is capable of referring reliable candidates, and thus have implemented the friend referral system. At ENI, one in five people is hired through the friend referral system. When a friend joins our company after an interview with our sales representative, and starts their temporary employment, we provide both the referred friend and the referring person a token of our gratitude.

ENI also actively implements online interviews using various web tools. Considering the risk of infection, we believe online job searching is an essential tool for swift job changes.
