Intense

Context: I have about 2 yoe (internship) and I'm now a senior getting ready to graduate in the fall. I just started a full-time internship where it feels much more like a new grad position than an internship. Which actually is not bad in and of itself. What I am concerned about is my ability to keep up. I'm a fairly experienced dev, particularly in the Rust OSS space, but pretty much from day 1 I'm having to help create a design doc to convert our current data flow from writing a particular data file/format on disk to generating it on demand for our customers instead. Very much architecture, system design things which is not something I've ever had to do before professionally. I'm needing to pick up what feels like way too many things in our stack. AWS; IoT, Lambda, Shadow, Firehose, Kinesis, Grafana, InfluxDB, DynamoDB, API gateway, etc...CAN, UDS and TCP protocol as well... On top of all of this, while the project I'm working on is in Rust, all of our code is in Go. So now I need to learn that, protobufs (because we use them everywhere), and their 100k+ LoC codebase. On top of THAT, we're going to generate this new data on demand using flatbuffers, so just as I'm picking up protobufs, now I have this new format to throw my head against the wall with. So far in all of the convos with my manager, I've genuinely had to let him speak the entire time because I just have no clue what the hell is going on. I just nod and smile. Again, the reason I'm not actually really concerned is because objectively speaking, I know this is the right environment to be in to become a competent dev... But at the same time, I have no idea where to start sometimes when it comes to asking questions and familiarizing myself with the work. I've been encouraged to download AI since we get practically unlimited access but I genuinely have zero interest in talking to an LLM all day to help me get up to speed on this stuff. I guess this is just a venting session for me more than anything. Is anyone experiencing something similar? Was it like this for everyone who started a new role?
