...to think that 10 weeks in a new role isn't that long?

It depends on the role but 10 weeks is a long time to still be asking questions like a newbie especially as you would have had to prove that you’re competent at the interview for you to be hired for the role. Many places have 3 months probation and that’s because in that time, you should have picked up lots of things.
Also when someone leaves a role and a new person starts, the other team members would be doing more than they should as they’ll be trying to cover for their work so by week 10, they’ll be getting fed up that the replacement is still not up to scratch

I don't think it's possible to judge without knowing what your role is.

10 weeks might not seem long to you, but it's a very long time for your colleagues if you are constantly asking questions and pulling them away from their own work. That might explain the change in atmosphere. They were happy to help and support, just they didn't expect it to be going on for this long!

It depends on the role, how different from your other experience and how competent you are doing the role and coming across etc. What is your probation period? When you spoke to your manager, did you ask how you could improve?
I would think by 10 weeks, you should have a fairly good grasp of the role and being doing it competently.
Unless its something so niche and specialist like a fugu chef, and takes many years to pass exams and attain?

Unless it's something like Brain Surgery, by 10 weeks I'd expect you to be doing all aspects of your position. accuracy & speed are variable on the actual job, but no, you really don't have the time to be fanning about 'taking your time'. This isn't the public sector.

you really can't say you've been ignored. You said yourself they were kind, friendly, supportive 🙇🏻‍♀️🙇🏻‍♀️

they're getting fed up of you not pulling your weight & likely repeating themselves.

If you are on a 3 month probation period, and not completely up to speed at week 10, I would prepare yourself for your probation period being extended or even to be let go.

Even with a career change, most employers would expect a new starter to be well established by around the 6-8 week mark. It’s unusual not to be comfortable in the role at 10 weeks.

After 10 weeks you should be doing most aspects of the role competently and at appropriate speed compared to colleagues doing similar roles at similar levels. (And if not at speed then making up time outside of hours until you are at same or better level of output).

It’s sounds like you’ve been focusing too much on understanding “really learn & take my time” rather than aiming to be as productive and competent as your peers within the first few weeks.

After 3 months most businesses have a strong view on whether someone is going to work out based on how quickly they’ve picked up the role and doing tasks. You won’t be expected to do the role as well as someone who was there years but there will be a trajectory that they will expect you to be on, especially if you aren’t the first new hire and it sounds like you are below par unfortunately.

It depends what the job is. Some require you to be up to scratch as soon as you start, some you can hide in the background for a bit.

Someone is about 8 weeks into an important role at my work and is constantly “overwhelmed” and other staff are therefore helping a lot. There’s no time for that unfortunately. She’s the only person in her role so anyone helping is doing that on top of their own job.
