I worked for Interac for 2 years. The salary and benefits are more than adequate because the cost of living is very low. The managers and staff at the Interac head office are extremely professional and helpful. My concerns were always addressed promptly. Working in the public schools in Japan was amazing. The kids are extremely polite and courteous and respectful, far more than kids in America (at least from what I recall from my days as a student).
The best part is making the kids laugh and being able to play sports or play on the playground with them. It's also rewarding being able to help tweak their pronunciation mistakes.
If you're looking for adventure before you start 4 decades in a corporate office, this is a good place to go. Interac is a huge company which is almost doubling it's teaching staff because of the upcoming Olympics. Very stable company, honest bosses. No surprises.
