never heard of a bonus like that in tech. only in sales and exec positions. biggest bonus i think ive ever seen in tech was $1-2k, usually i'm lucky to see a few hundred bucks.
We do 15-16.5%, and I'm not on the sales side either. My previous job didn't, but they did referral bonuses and rather hefty certification bonuses.
Negotiating salary sucks so bad. When I was approached by my current employer they gave me a pre-screen questionaire and I put the most asinine number as a salary number on there. Then the next 4 months of technical screenings/personality interviews/etc went and never was there a mention of salary so I assumed that I was going to be alright.
Keep in mind this wasn't just any company but it was THEE company I dreamed to work for so when I was told my offer letter was being prepared I prematurely started the celebration amongst friends on my team. I watched my email like a hawk and waiting for the email to come in and low and behold the number was 38% less than I put on the thing and only 20% more than I was currently making in my current position that was 0% travel versus this one that was 75%.
I remember just smashing my face off the desk after 5 months of torture was over. Although it was my dream company I knew that it wouldn't fly at home. So I sucked it up and told them that I would have to deny the offer and that I was sorry. I was devastated as I had my heart set on the opportunity to work for the industry leader of my niche of IT and now it was over.
Well, fortunately they called back within not even 4 minutes and shot that number up to an amount that was effectively a 65% increase from my current. Needless to say I definitely accepted it.
Lesson learned, they went that far and kept their cards close but never take the first offer. I had later found that I was against 12 other candidates, so there was some luck on my side that day.
I know this post is a little too late as you already landed your position, but I figured it was appropriate to share the story. Congrats on the new gig!
