Recent undergrad from a T1 college, non-tech. Joined a big 4 firm through campus few months back.

Training was around 5 weeks. I could understand the concepts and complete the assignments, but I found the actual work quite non-stimulating. The team was entirely WFH, with trainers, managers and peers scattered across cities, so there was very little team interaction + no in-person orientation. Coming straight from college, I found the remote transition difficult.

The issue came during the final assignments. There were time limits and a permitted failure threshold. I became overwhelmed under the constraints and failed more than allowed. Management subsequently decided I shouldn't continue in that department.

The silver lining

My manager has said twice they don't view it as an effort issue and believe I genuinely tried (backed by the trainer in a separate conversation).

Instead of putting me on a PIP or exiting me (did explicitly say in that conversation that this isn't the end for you), he reviewed my original CV and felt I may simply be a poor fit for highly process guided work. He also highlighted positive feedback I'd received from a director during the hiring process and had originally been shortlisted.

He's since been actively trying to find me an internal role that might suit - I've spoken to managers from another vertical and completed assessments for a potential role there.

Problem

I'm currently in limbo. I've had essentially no substantive work for 2 weeks while these discussions happen. I'm staying logged in and available, and my manager has continued setting up meetings and trying to move things forward, but I don't have a confirmed role yet.... the uncertainty is pretty demotivating.

For people who've worked at Big 4 professional-services firms:

1. How common is it for freshers who don't clear final assignments to be internally repositioned
2. Does management actively trying to find another role generally indicate they still see potential, or can this happen before eventual push to quit myself.
3. At what point would you stop waiting, and should I start looking for other opportunities in parallel?

TLDR: Fresh grad at a Big 6, I couldn't clear the final training assignment for my role and was moved out of the department, which has left me disturbed and uncertain.
My manager doesn't see it as a willingness issue and is actively trying to find me a better-fit internal role, but I've been sitting idle for over a week with no confirmed outcome.
Am I genuinely in trouble, or is this a normal-ish internal redeployment situation and should I start looking externally while I wait?
