As an inspiring leader, we asked Brenda a few questions about her time at Waterloo, career and advice for the next generation of women looking to follow in her footsteps.

Why did you choose Waterloo and the Faculty of Mathematics?

I had an early love of math. I enjoyed the ability to “deduce/prove” things with logic skills without a need to memorize a lot of information. I also wanted a program that would allow me to study math without having to do a B.Arts or B.Science as I didn’t want to study science or write essays at the university level. The Bachelor of Math degree was very unique certainly at that time. The co-op program was also a draw.

How did Waterloo help you prepare for your career?

I gained confidence by surviving the rigors of the program at Waterloo.  I’ve always been proud to tell people that I studied math at Waterloo. The co-op program also allowed me to get an early taste of accounting and exposure to lots of CAs (Chartered Accountants) who shared their experiences and expertise with me.

What’s the most interesting thing you’ve done professionally since leaving Waterloo?

While I was working at Ernst and Young (Professional Accounting firm) in Palo Alto, California, I was involved in their “Entrepreneur of the Year program” and got to meet and participate in the interview of Larry Page and Sergey Brin – the 2 founders of Google, Inc. (2003).  I was also the audit manager on the Google account when it went public in 2004.

What do you consider to be the most useful piece of career advice you ever received?

I have a few. Work hard, be curious and ask questions. Deliver a high quality product but don’t aim for perfection, it will slow you down too much! Seek out feedback and be receptive to it. Double down on your areas of strength, don’t get overwhelmed with areas of weakness, we all have them and it’s good to know them.

What would you tell other young women choosing to study math or computer science at Waterloo?

Go for it!  You will find lots of other like-minded people in your program who enjoy similar studies and challenges and make life-long friends.  You will also develop your problem-solving skills that will help you in many ways.
