I am in an external audit internship/articleship since past four months. I've been humiliated several times for not performing deliverables on time, as compared to the experienced ones(considering I had worked in an tax return preparation role before, which was unrelated to auditing though). I, however managed to learn to do it faster, only to be assigned to an internal audit project, where I have to learn everything from ground zero. The senior, even though acknowledging my lack of experience, still expects me to learn stuff and deliver at a faster rate, which is fine. However, now two of my other team members are going to go on leave, leaving me to handle the project alone for a couple of weeks. I am scared at the moment. Any advices, please?
