I asked an uncle about buying a suit for an interview and he said to avoid polyester as well. How do you manage in the Texas heat with a 100% wool suit? You are going to inevitably have to walk outside for 15+minutes and you will sweat profusely.
For a summer suit, avoid polyester. It actually does NOT breathe well (tropical wool breathes much better).
Good summer suits are often made of linen because it is really thin and light (but it wrinkles).
And yes, polyester is not always bad, especially if it is blended with wool it can help resist wrinkling. However, often polyester risk looking cheap. I guess a good polyester suit may be preferred over a bad wool suit. Then again, at the end of the day it is about how the suit FITS you.
Wool is just the gold standard for suit materials.

Choosing The Right Suit: Fabric
Below is an extract from our Interview Guide eBook available at

Choosing The Right Suit: Fabric
Wool
A quality wool is the most appropriate fabric for your interview. Wool is
resilient, crease resistant, drapes well and is relatively long wearing.
Wool breathes, is comfortable in a wider range of temperatures and
has an elegance that cannot be duplicated.
Other Fabrics
Fabrics such as silks, linen, rayon have their place in a less formal
environment where one wishes to make a fashion statement.
Polyester on its own or blended with wool can be presentable but may
feel like you are wearing a plastic bag. It is also likely to pill.
A quality microfiber, a fine fiber woven from polyester or a polyester
blend, can be woven to breathe reasonably well but does not have the
elegance of wool.
