Simplus is a Salesforce consulting firm, and yes, sometimes tech consulting is very stressful. We can have demanding clients, we can have projects with high travel, there are many inherent attributes of consulting that make it "stressful".
Many of these things aren't the fault of Simplus, it's just a demanding industry. The exact same stressors exist at competing firms - most of them even more so. You will be out of your comfort zone, you will get stressed out. But each time that has happened to me, I toughed it out, I leaned on coworkers and friends at Simplus, and always came out on the other side.
From my coworkers to my managers to the leadership team, I'm having a tough time thinking of many 'cons'.
