The PhD and MS stuff is not being asked in interviews. Yes, that stuff is hard. Tech interviews are 40 minutes max. There is only so much stuff that can be asked and programmed in such a short amount of time. The stuff being asked in tech interviews is "traverse a tree in this interesting way". There are only so many ways to traverse a tree. And no, I am not talking about crud interviews, I am talking about Google in…
Tech interviews are 40 minutes max? Where are you interviewing? I have seen far more 6+ hour interview loops that 40 minute ones. Maybe each session within the full loop accounts for 40 minutes. That being said, people have their pet questions they use to sort the wheat from the chaff--if you can't fizzbuzz your way out of a wet paper bag, I am not hiring you. The best questions are more about process than the final…
Usually 20 minutes out of a given hour long interview is just BS resume and chit chat.
And yes, there are often 5-6 interviews in a row. But that still leaves the fact that there is only so much that can be covered in an interview with 1 person in the 40 minutes you are given to code a problem.
And those 40 minute coding problems are all taken straight out of cracking the code interview, most of the time. Even at Google.
Process questions are good, and conversational interviews are also good. I wish people would do more of them. But unfortunately it is mostly just algo questions that you have to cram for.
