I've been recently hired to do web development, something that I always had interest in but did not have any experience outside of studying on my own time. I am very thankful for this position and I feel like I am doing a good job here, I feel like I am displaying a high capability for learning quickly, legitimate interest in the problems presented and effective implementation of solutions.
However, I have had no real feedback on my work, and I don't have a real notion of how well I am meeting my employer's expectations. Would it be acceptable to ask my superiors how well I am being perceived in the company? If after this month that passed I am considered a good hire? I am curious to know and I am also open to any criticisms that I may never be aware of if they don't tell me.
I want to know if this is a common or acceptable request for a recent employee to make, and if so, how to best do it?
