If you’ve decided to transition from engineer to technical manager, your first month is about committing to own your education. I'd argue replacing "first month" with "first year and beyond".

An important thing I told people is how they themselves own their career progression - they should be coming up with the goals as well as executing on it. As a manager, my role is to help and support with this process - but they will own driving it.

I also talked with people about where they would like to grow, things they like and dislike doing at work and in where see themselves on the longer term, beyond their current role or company.

I didn't have to think too much of what’s good for the company - I usually assumed that whatever I’m doing is what the business needs.

I don't think there are universal answers and the expectations will also vary from company to company.

It would take me years of hard work to get from this junior level to something more senior. Looking back, it is also clear how mentors helped me grow much faster professionally - most of whom I've met by chance on the way.
