I worked at Targa full-time (More than 5 years)
Great Company to work for.
None that I can think of.
Advice to Management
I applied through college or university. The process took 2 days. I interviewed at Targa (Houston, TX) in March 2016.
Make sure you know the company and get comfortable with behavioral type of questions, but the interviewers are very nice so they will make you feel more comfortable. Come in with questions to ask. Overall just make sure you prepare prior to the first interview, you only have one chance to get into the second round of interviews.
