I have been working at Lexmark International (More than 10 years)
Great people. Generally good management. Ethical culture. Competitive pay. Good benefits (unlimited "vacation"). Vertical market approach provides opportunity for some focus. This company genuinely looks to do the best they can for customers so I never had to make silly excuses for our performance or products. Good diversity (age/sex) on the software side of the house. Outside of the current bid to sell the company (killing morale) it is one of the better places I think one could hope to work. Relatively low turnover.
Growing pains from M&A activity that have consumed 15 companies in 5 years. They have not been careful enough with these cultures - with the "secret sauce" that made these smaller, more dynamic companies worth acquiring. Much harder place to work if you are in sales as management has a lot of focus on Salesforce reports - not unique to Lexmark but still often shortsighted.
Advice to Management
The companies you purchased are more than technologies - they are cultures and people. Sales teams and territories are constantly "optimized" at the expense of sales people developing long-term relationships. Sales cycles are longer than the annual musical chairs activity.
I applied in-person. The process took a week. I interviewed at Lexmark International (Lexington-Fayette, KY) in July 2015.
A mixture of behavioral and technical questions. The technical questions were all based on my technical research/ experience listed on my resume. How formal the interview is is dependent on your interviewers. Two of my interviewers were very laid back. The conversation was very relaxed and informal. The other two interviewers were more formal.
