Stressful for you, may not be stressful for someone else. Also, in my exp your manager, boss, lead has alot to do with the amount of stress. Also, try to not let these things stress you out.
When you start having phone interviews, make sure you ask the hiring manager this question:
How many people do you manage? how many people have left your team (for any reason whatsoever) in the last 12 months. This number is quite telling. Good companies and good teams don't have attrition and don't have problems keeping employees.
Not always true. My last team was atrocious but nobody ever left because they were held all captive on their H1-B.
To explicate a little, I've found stress mostly relates to the expectations of people around me, and has very little to do with the difficulty of what I'm being asked to do.
