I am a M[31] "senior" software engineer with about 6yrs experience working in the financial sector. I say senior but I dont think I am really at that level yet. Most of my experience is in data engineering (python, sql, cloud etc) but I recently took a position as a senior engineer doing full stack work juggling multiple frameworks (django, Node.js, Laravel PHP) django I knew some of coming in but nothing of Node or PHP. I have been at this job for 3 months now.

When I am working with my co-workers and they are explaining code it seems to me that they are irritated and or disappointed with my current skillset and level of understanding. It takes me longer to understand things than I think they were hoping and this is really demoralizing.

I mentioned this to my manager saying I feel overwhelmed and I am trying my best to get up to speed with our codebases. I also mentioned that I feel like my team is basically saying "how do you not get this code yet?" and "I thought you would already know this." My manager has said he will discuss with the team to see where they are at with my progress and their thoughts on me.

I have been getting frustrated answers from the team when I say I still dont understand a process fully yet and need more time.

How would you handle this situation?
