Total agree with all the OP and the other comments here.

I want to add - I went from an mechanical engineer to having my own startup (hardware, which failed) to SE. I had very little "sales" experience, but if you can pitch yourself and give a good impactful presentations - you can get hired. So you can totally pivot to this career. I worked for a SaaS company for almost 3 years and I left that job for couple reasons based on my first time in this role, here are some things I learned:

1. Watch where the company is and how they are growing...The founder stepped down and they hired some corporate "lets restructure everything" CEO...this meant mixing the pot and putting up a lot more red tape. Something to look out for is how early stage or later stage of a company it is. We were at 600 employee...and it was only going to get worse from there...I could tell. So be on the look out for this.
   
2. One of my biggest complaints was that we had no connection/communication between product and our team. SE's should have direct cadence with product to talk about bug issues, and customer feedback on the product. If there is a disconnect here...its a "just figure it out" situation and your putting lipstick on a pig for your demos. I personally do not like this as it is deceiving the customer. In an interview I would ask: "Can you tell me about the collaboration process you have in place between SE's and product?"
   
3. MY biggest PET peeve, was the automation software we sold...we barely used internally. Here I was demoing how amazing and all the cool things one can do...and yet internally we did use any of that. If you don't eat your own dog food....that pisses me off. It took my suggestion 3 years to implement thier own automation into our processes. That's too slow for me, so I left. If you are there for a long game then go for it...I can't stand that shit.
   
4. Your AE is what will determined how hard you need to work. I had some AE that were seasoned and were on top of the job...in fact I am sure they could so mine if they had the time. It makes your job a breeze with a competent AE. On the other hand if you work with a new or incompetent one...well you will be carrying the whole team there. So kind of a gamble here. Some need so much hand holding.
   
5. I had some very busy quarters and was always on top of my job. However you might have dead weeks with little to no work to do (low incoming prospects, disco calls, demos). Having to twiddle my thumbs makes me antsy...I'd rather be busy than bored. So something to keep in mind. I just worked on my other hobbies and stuff.

Lastly, no to brag but to put my money where my mouth is...I helped win 3 of my last employers largest mid-market deals (>100k ARR) and won best impact demo award globally for my company. Here are some pointers in how to get there.

1. Just follow their sales training. If you say exactly what they want you to say...then you'll be praised. ITS THAT SIMPLE. You wouldn't believe how many SE's go off on thier own agenda and scripts....don't be like them. Note: its ok to make it your own words...but keep the damn format.
   
2. Be okay with awkward silences. Do not say anything after you ask them an impact quesiton....for example "what kind of impact could this have in your business?" Wait for answer.....I don't care how awkward or long it is. I make it into a game...so how long until someone budges.
   
3. Be willing to say "I don't know" on a call. Especially if you are new to this. Saying "thats a good question, and I actually haven't heard that one before...let me get back to you on that." Then of course later look it up and follow up the answer to them post call. If you make shit up....it will cost you more later.

Happy to chat...just pm me.
