Not enough people on the team to handle the sheer amount of Google client work. Most of the time, senior leadership meets with clients - taking away opportunities for those in junior and mid-level roles to learn through client interaction and engagement. Doesn't give new employees nearly enough time to learn client needs and industries. Asking questions to best understand how assigned tasks ladder-up to overarching client goals and priorities is not looked at favorably.
Managers are not properly matched to those they manage - i.e. employees in the Creative + Copy dept. managing those in the Intelligence dept. (etc). This creates a disconnect by not allowing those being managed to learn more about their craft from their managers, or be able to ask them questions about their work and gain real-time feedback. There is also a lack of tapping into teammate strengths and aligning these strengths with client work... There is value in placing employees into projects that they are unfamiliar with - which would help them grow in their skill set. However, doing so without having understanding that the employee is not in their element and is still learning, and judging the work as though the employee is well-rounded in that skill and thought-process, is unfair.
