I’m not going to define the role of a tech lead but one would think that a tech lead is part leader of people with technical and subject matter knowledge. There are things a tech lead should not say or better tech leads who say these things might not be qualified.I forgot my database classesI think the language supports that featureI did a little reading last nightI don’t mind that you’ve forgotten something or you might not know or remember all of the details; however; do not offer an opinion until you are refreshed.Doing a “little” reading is useless. That’s going to give you enough information to be a meme and not a leader or innovator. You should be reading regularly and a lot.I’m not sure what to do when a programmer says:I cannot code without an IDEI need a debuggerYou’re still a beginner if you cannot write, compile, and test your code from the command line.
