Phone interview was with HR and it went extremely well. Basically, we discussed my background and how it aligned with the current position. No difficult questions we asked as it was straight to the point and the HR representative was more interested in my background. A day later, I received an email in regards to a 1:1 interview with the hiring manager. The interview with the hiring manager was not easy. Lot of "on the spot" situational questions. Like, you have work for 6 months to get in front of this customer, he/she picks up the phone. What do you say? Go! Also, you win the deal, but the procurement department informs you that your price is too high and they need to have two other vendors price the project. What do you say? Go! Overall, both interviews went well and I did well it both but the candidate who was hired did a better job and had experience with the existing customer base.
CT Coporation is a great company and has it stuff together. If you go for a job interview, make sure you study the products and services they offered. I did not and that was a hit on me. Do not get overwhelmed with the situational questions and prepare yourself for that style of interview.
Hope this helps and good luck.
