The only pro about working in this role is that you will be exposed to all facets regarding Oil & Gas business practices.
Desventajas
This is a highly demanding, pressure-cooking job and the pay is not worth the hassle to the lack of work-life balance that you will experience. Executive admins will make significantly more salary and only support one c-level exec whereas you will have to support all the executives and their admins. You will be pulled in so many directions and will not be backed up by IT management. You are literally on your own since no one wants to handle or interact with executives since there are walking land mines everywhere. You can provide the best customer service and will be back-stabbed and bad-mouthed by minimally talented executive admins. There is a long history regarding this IT Executive Desktop Support role. You will be told that they could not find the "right person" but the truth is that no one that has ever worked in this role has lasted longer than a year. This role becomes open year after year for the next unsuspecting prospective employee. It is shameful that Apache has not corrected this issue but this is very telling regarding their management and culture.
