Your real problem is that you've had no mentors and that's not your fault. Software people need good mentors. Always being at a place with few or none programmers never gave you the opportunity to learn by example and that 10 years wasn't very valuable. You have probably grown some bad habits and lack the understanding to recognize them. If the people you are working with now are nice then you should take this as an opportunity to become the senior engineer you thought you were. Hiring people is annoying and if you are personable, humble, and eager to learn more often than not they would rather train you up than get rid of you. You did the fake it part, now do the make it part.
