Are you currently applying for or considering any other jobs?

"I am keeping an eye out for viable positions where my skills can help a great pharmaceutical company. Although I am not in the final stages with any other company, I am actively seeking a new position with an organization with a solid industry reputation and room for career growth in the future."

"As I considered many great pharmaceutical organizations in my initial job search, my research on corporate values, product lines, and details of the job led me to Allergan. This is the only application I have submitted, and I'm hopeful that this opportunity works out for me to join your awesome team."

Tell the interviewer about your search so far and be honest in your approach. Let your interviewer know if you are currently applying or interviewing for other positions. While you don't have to divulge names of other organizations you are considering, discuss where you are in your overall job search and try to convince your interviewer that Allergan is at the top of your wish list.
