I recently changed from a 4 year consulence as Data Engineer in a big consultancy firm to a Data Analyst Role with Tableau and PowerBi in another consultancy company for a stable contract. In previous company everyone believed in me because by mistakes and trial I managed to become a good,reliable and fast with several raises to salary. Performance reviews were good and I've always managed to become better. Now in this new company I managed to pass the trial thanks to me shortening some tasks of one week and by getting two certification in first month. I'm the only data analyst in the project. Team is mostly formed from non technical peoples. I've been assigned some tasks and I did some mistakes due to lack of knowledge domain (not technical but functional) : there is no documentation on where data is, the model and the flow of data. They gave me some guidelines on how to do the task but I still have to interpretate what my manager wants and ask to several peoples pieces of information to get my job done. To become fully operative I used 4 days(getting access,understanding domain)and thankfully there is a non technical colleague that is explaining me the whole flow and domain, helps me in a functional knowledge to get my work done.
I know that I'm a Junior, I'm open to become better and that I'm not fast and quick as a senior data analyst.
I feel at the same time stupid, but I'm managing to do the job and still clash with the lack of help from team in something that for them is easy.
I feel that they expect me to do the job with the speed of a senior, but I don't have a senior supervising me, so I'm alone with my speed, knowledge and mistakes.
Mood is low and I don't know if I'm being too harsh on me. Sometimes I feel that I'm not fit but I tell myself that I'm still working and completing tasks after 4 years. I don't understand if these expectations are correct, are they right and I have to tough up ?
Thanks for any suggestions
Tl:dr - struggling with short term projects, lack of supervision and help
