Applied online via the Northrop Grumman careers website. Contacted by hiring manager via email a few months later. Initial phone interview with hiring manager and an RF systems engineer. Brought in for an on-site interview at the Rolling Meadows facility a few weeks later. Met with HR representative for a few minutes, followed by a panel interview with six or so employees. Mixture of functional managers and RF and EO/IR technical personnel. Asked to give a general overview of my experience / skillset, followed by a couple questions about my resume and some situational / behavioral questions. Opportunity to ask questions. Afterwards met with one of the higher up EO/IR managers, before finishing up with HR. Short tour of the facility to see the cafeteria area and new gym with showers. Whole interview took about 2 hrs. HR said they would be in touch. Followed up with HR via email a few weeks later. HR representative was kind enough to let me know they were moving in another direction. Post interview treatment with regards to travel reimbursement was less than professional. Since I was traveling from out of town, HR had me contact the corporate travel agency to make flight, hotel, and rental car arrangements. Normally, this is billed directly to the company. Unfortunately, the hotel that they normally use for direct billing was fully booked, so I had to pay for the hotel out of pocket. I was told by the travel representative and the Northrop HR representative that this would be reimbursed. After the interview I mailed the receipts for hotel and other expenses to the HR representative as they requested. Three to four weeks later I sent an email to the HR representative inquiring if they had received the receipts since I had not yet received reimbursement. When the HR representative did not respond after a week, I sent another email to both HR representatives inquiring if they had received the receipts and were able to get the expense report into the processing queue. When I did not hear back from either HR rep, I sent an email to the hiring manager inquiring if he needed anything else from me in order to process the travel expense reimbursement. It has now been over two months and I have not received travel reimbursement or even an email from either HR rep or the hiring manager with regards to the expenses I submitted. As I point of comparison, I later interviewed with another Fortune 500 company and was reimbursed for travel expenses within 11 days. If you do interview with Northrop and have to travel from out of town, you may not be reimbursed for meals, hotel, and rental car gas even if they tell you that they will reimburse you beforehand.
