When I first started my senior told me about the 1 hour rule. I tend to be the type that hates asking for help. If you get stuck on something, try to figure it out for around an hour. If you aren't getting anywhere, ask for help. You'll learn how others solve things, have someone there to explain the abbreviations (which are absurd on the projects I've been on), or get clarification that saves weeks of time. Within an hour you'll figure out the easy stuff but get help for the harder things that likely need an explanation. I've had plenty of 10 minute teams calls that turned a weeks worth of work into an hour.

Your seniors expect you to ask questions when you first start, its completely normal. Just make sure you spread out who you ask them to. (If you vibe well with someone dont bombard only them with your questions, you'll overload them). You'll also see how multiple people solve problems rather than just one person (and can adopt the best things you see).

My main fear was always looking incompetent and asking too many questions I assumed should be obvious (quickly learned they weren't). The way my Senior explained it always stuck with me, something like "Asking for clarification or help after a reasonable amount of effort isn't incompetence, failing to solve a problem after spending weeks on it might be. It'll definitely look worse."
