It's not impossible to overcome, but it does take time. Time your earning less money than you would be.
Time to build up a competitive resume so you get an interview despite a lower GPA, and time to study so that when you do get the interview you leave a better impression to make up for the poor GPA.
Generally the whole "GPA" importance concept is crazy to me, because in my country I've never heard anyone ever being asked about it
I don't even remember my GPA because I've seen it maybe twice - once when I received diploma and second time when I've been going thru my documents and just wanted to check out of curiosity
It's so flawed metrics that I'd never even consider it as reasonable when interviewing people
In my early career I've had several recruiters who were very interested in me based on my resume, had several conversations and then when they found out my GPA said they couldn't place me.
Also had several jobs I wanted that required a certain GPA even 5-10 years into my career.
what. the. hell.
I hate that mindset with passion.
Folks, just skew the odds.
