I Participated in Campus interviews in various campus for last few years , In IITs students were asked to sit in a written test and interviews were conducted for shortlisted candidates. The input was mixed group of B.Tech and M.Tech.
Branches we targeted were CS , Electrical , Communication or related fields for M.Tech such as VLSI , DSP.
My observation was simply based on the interviews conducted.
A few samples common questions out of my memory.
1. A student did his project for Image noise removal , I asked him how do you define Noise in case of Image ? No clear answer finally he said suppose it is 8 bits grey scale image then values will be from 0 to 255 so when it is 255 it is a noise. On further digging if you are clicking picture of a white board or black board ( depending on what is 255) will it be image full of noise.
He remained silent.
2. What is difference in time domain and frequency domain ?
With no answer forthcoming asked directly do you remember Laplace and Fourier transforms ? The answer was no , How exactly they studied DSP and Image Processing is beyond me.
3. For Computer Sc. students
(a) Asked to design a clock going to hour and day deriving from a lowest level tick ( assume 1 sec tick) ? Very few students solved this , No code was required only asked to explain with pen and paper the approach taken.
(b) Asked a few questions on System Design and asked do you necessarily need an OS ? The answer was invariably yes then when I asked then how come micro-controllers and programs in toys work they had no clear idea.
(c) More direct question on services provided by OS were often replied in form of what a PC OS does including TCP /IP when I asked is it essential service for OS answer was yes in 90% of cases.
After this when I asked what is difference between Micro Kernel and Monolithic Kernel very few people realized that answer to previous question was incorrect ( and they were shortlisted for realizing it)

Based on empirical results after interviewing few dozen of Phd candidates.
My observation is people who go for PhD after some work experience voluntarily generally are better others simply did Phd because they could not secure job after graduation and after a gap of couple of years higer studies was a necessity.
Few common red herrings
(1) The problem description was too simplistic or the thesis was mostly a comparative study.
Example: A Candidate submitted 32 page resume with everything under the sun in Cloud computing with all essential keywords such as SODA , SOA , Internet of Things etc. with the description of the term from Wikipedia but no description of what exactly he did.
On asking what is your contribution or work in these areas same lecture on cloud computing was repeated.
Probed further but similar response so finally after few iterations gave up and said thanks for your time.
(2) The development was done on some open source but could not clearly identify what capability particular research added.
(3) No patch ever submitted back or questions evaded citing that blah blah is confidential ( if it is confidential how exactly you submitted your thesis ? )
(4) A common question asked was where can you apply your research giving certain broad situations , Again no answers.
Disclaimer I am myself not a PhD but some of the things were too basic.
