I cannot speak for Lambda specifically... but have been on interviews on the other side. When your only technical understanding as a developer is literally what you were assigned, with no personal effort beyond that, you will be very unlikely to be able to fit into most development environments, which imho requires a certain amount of discovery, research and ongoing reading. You cannot just sit on your knowledge for 20+ years in this career path... some come close, but they hit a wall... I've also seen that when interviewing those with 20+ years of experience with nothing more recent. In the end if you cannot/will-not grow, and this can include taking time during work hours, you won't succeed. When you're starting out, you have to bury yourself with learning to get a leg up for at least a few years. Later, you can get by with reading a few articles a day and maybe a couple experiments over a year. But you can not stop learning. And not putting extra effort in when starting out, to me at least, is a bad sign that you won't do well without someone holding your hand.
