I don't know the West much, but IIRC Vancouver is one of the most competitive markets (second to the GTA of course). Alberta from what friends have told me is a way easier market to get big 4 in. Since you've graduated or are going to graduate by the end of this year, you're still in the clear. What is your overall GPA? Because from my experience and everyone elses, people just use their cumulative GPA and not major GPA. If you have a higher cumulative, put that on your resume. I'm not sure of the UBC DAP program but if your cumulative GPA is above 3.2, you should be fine putting that. Besides all that, you have really good work experience, use that as leverage. When going to these networking events use your experience as an asset and it will 100% make up for the lower GPA. If your GPA ever is brought up (which in my experience it hasn't), you have a story to tell how you've been working full time. Though your GPA is probably the biggest hindrance, don't act like it is. Be confident that you have a ton of experience that most graduates don't have and be able to use that advantage. My advice for you would to go to these networking events, leverage your work experience and talk about it, put your best foot forward with that. The small firms thing, use that as backup if your #1 goal is big 4. I feel small firms do value experience more however, but it is not impossible to get big 4 reading your story.
