Give more than you receive. Help your peers, help an adjacent team, help recruiting. Efforts and Time are within your control to dispense. The ability to care for a product / company beyond the work/pay trade, to be vested in the product's success, the learnt skill to obsess over the minute details and to suggest improvements in features or processes - your past grades have nothing to do with these traits. Any / most of these dimensions would make you a valued team member.
