For any career path you may choose following are the certain experiences and skills I look for in my experience.
1. Dedication to learn and adapt.
2. Risk taking ability and situational based decisions
3. Be open and bring in ideas to table to develop more constructive discussions .
4. As a technical manager, one of the key skills needed are collaborative skills to talk to different teams and make sure everybody are aligned.
You could gain this experience from your schools projects and assignments by being a group leader or group member. Hope this helps.
