I totally agree. I think we are just using the term transparent differently.
Telling people to go on a random walk for a few years and maybe they will move from mid to senior is the kind of transparency you get in tech.
Real transparency would be: If you deliver project X and can demonstrate you got Joe and Raj up to speed on Y then we will promote you/increase your salary/give you a big bonus/put you on the project you really want etc.
I agree with you too. I've never seen a job in tech where it was clear what it took to get to the next level (either salary-wise, responsibility-wise, move-into-management-wise, etc.). It's always hand-wavey "do better and who knows!" or "you'll be senior engineer after a few years!" type guidance. Sometimes I'm jealous of folks like salespeople who have clear metrics. Pull in $X in sales and your bonus is $Y. Bam! That would be awesome.
