TL; DR:

• Constructive criticism is hard to give -- If you're not getting it, ask for your biggest opportunities to improve.
• Tech lead or Manager roles require different skill sets and more time working with people, not code.
• Clarity around timelines and milestones can be very situational -- don't be afraid to ask for more details on due dates.
• You need to be in the driver's seat of your career, because certainly nobody else will do it for you.
