This is according to me in my specific situation. My junk is different from yours so we might have different experiences.
Ask in the comments if you have any additional questions.
1) What is the process?

2) Does it hurt?
Yes. If done traditionally, you have a needle inserted into your junk and floods of pain issue (like a normal shot) with the injection. Various times during the surgery, I felt extremely sharp pains combined with lots of dull pains. Not a good time, but well worth it.
3) Shit they skim over.
You are awake and hear and feel what is going on. You hear them snip the vas deferens, you feel the heat of the cauterizing tool, smell the burnt flesh, feel your insides being yanked around like you are a "Saw" victim. It is unsettling if you are weirded-out by that sort of thing. Take some meds (if the doctor tells you to) to reduce anxiety. In a developing nation, I didn't get anything besides a local anesthetic which was only marginally successful at dulling the pain.
4) How long does it take?
About ten minutes per side.
5) Drive home?
Get someone to pick you up. You won't be moving very fast and don't want to drive a car.
6) Recovery ?
Everybody is different. People want to claim you can get out an about in two days. That was not my experience. Remember, it is your junk we are talking about. A little bit of pain means get the fuck back to bed. Do you want to man up and possibly damage your love maker or relax and make sure that you have the rest of your life to have carefree sex? If you work construction give yourself at least a week, possibly longer. Get your boss to okay an extension if you need it. If you work in an office, maybe you can do your job sooner. I work construction and don't know how it would effect your job performance.
Read the links online about the procedure and the mentioned recovery time but complications are rarely mentioned. I got the lucky draw I guess and had some frayed nerves to deal with. Instead of a week to feel better, it took almost three weeks. In fact, after a month my balls are still sensitive. Cats or dogs jumping on my balls is not fun and riding a motorcycle with ball slapping the seat over large bumps or potholes is still noticeable. Remember, this isn't your arm or a bum knee, this is your junk.
Maybe you will be like the normal guy who recovers in three days and fucks soon after, I was not. Keep in mind that you can easily be the marginal percent and plan accordingly. The worst that happens is you go camping or fishing because you took additional time off.
7) Sperm ?
Get yourself checked twice, once at 6 weeks (if you get a "0" then do it again in a few days to verify) else try it periodically after that. Get checked though!
8) What's it look like?
About the same volume but much runnier. It is also significantly clearer.
If you have ever jerked it in the shower, you would have probably noticed that sometimes have your mess "hangs" up on the grate/strainer, like a loogy in the sink. That stringy shit, isn't there anymore. Your mess is much more like liquidy sticky jelly.
9) Taste?
The online community suggests that you will taste roughly the same. Maybe even less semeny. I don't have the same partner I did after the vasectomy so cannot first-handedly compare. Sorry. I didn't expect to make this blog.
10) Physical Change.
If you have a traditional vasectomy there will be changes.
Your vas deferens will be tied resulting in (4) pea-size (or slightly larger) lumps in your sack. Two will be attached to your testicles where the tubes were and the others will be hanging around somewhere. (everybody is different). Mine are a bit sore but my friend (who had his vasectomy six months ago) reports no pain at all.
I notice my balls are much "freer". They hang lower and swing faster. Because of some nerves, in the process of repair, they are a bit more sensitive. Watching out for animals and kids for a bit. I will update this blog after a few months to tell what happens.
My junk looks bigger though with the added freedom so I guess that is a plus.
11) Complications.
Shit can go wrong. I am living account of it.
Read the warning from the links provided.
For those worried about cancer or dementia, the science isn't there yet and if it was, you have to ask yourself if a lifetime is living is worth one (out of thousands) of chances/ways to develop problems in old age.

12) Was it worth it?
Yes
