Life Time Senior Software Engineer interview questions

Sorry to say I had a very bad experience, actually 2, at Life Time Fitness / Athlinks. I applied a year ago for a Senior Software Engineer position. I went in for an in person interview which went well; it was straight-forward Java questions -- recursion, design a db schema, etc. They said they'd like to have me back in for a coding exercise, which I was happy to do (I've been a Java developer since the late nineties). When I got there, the exercises were in Scala. I reminded them that I didn't know Scala (their ad said it wasn't required). I offered to take home the test and learn enough Scala that evening to do the exercises and turn in the answers. They said I had to do it there, so I did my best for 1 1/2 hours, mostly thinking "I really should be at work". I didn't get the job. Unfortunately, I do have a male colleague who is also a Java developer that does not know Scala either who applied there at the same time. He was not asked to take the Scala test. He did get an offer. A year passed and I had been working in Big Data technologies which has been really great and interesting. I saw an ad for Life Time again. They were looking for a Java developer with Big Data technologies who wants to learn Scala. This one clearly said, learn Scala on the job, and I applied. Well, yes, this is getting to a "Fool me twice, shame on me" ending. I immediately got a response that they'd like an in person interview and that I should first take an at home coding exercise, which was great because I could see it was in Java. I spent the evening doing the exercises and submitted it. I got an email back that the job had been temporarily put on hold...then a week or two later it had been re-opened and they asked when I could come into the office. I provided times of my availability. I got a response saying that I had interviewed there a year ago and they don't want to have me in again...AFTER having me do a coding exercise. Very unprofessional and inconsiderate. I am curious about their development staff, because both of my experiences seemed very fishy, like they were interested in my technical qualifications, but... Fortunately the market's really good and it's not about getting that job per se, it's about how you treat people. Pros: They do have a very nice office in Louisville, CO.
