If this is for a job post in the US: It is illegal under U.S. federal law to discriminate against an employee, either intentionally or through a disparate impact, on account of his or her race, color, religion, sex (including pregnancy), national origin, age (40 or older), disability or genetic information.

US employees who believe they have been discriminated against can file a lawsuit, but it is difficult to prove and historically not viable.

A quick look at the Xoriant website shows they have operations in the US(mostly NJ and CA) and India. A non-native English speaker who is not familiar with US law could have posted this with good intentions ... but I do not think it is likely.

The job postings on their US website do not have this strange pattern of NOT's and all that mess, but they do have some minor grammatical errors and obvious incomplete sentences. The India careers site is actually much nicer. It has more specific requirements and clear qualifications. There is this sentence with the specific year ranges:

Job Description: Senior Technical Lead - (1800003277)

Role:
...
"As an experienced Big Data Technical Lead, you should have 12-16 years of experience in IT, with minimum of 3 years of full-time exposure in projects involving Big Data / Hadoop."
...

Perhaps they are using some dataset that shows the most successful hires for this job involve people with a certain number of years of experience ... less means "not enough experience - too much effort to train", more means "retiring soon - not worth training"

I don't know of a dataset like this, but it seems likely there is one. I would love to see it! I'm sure many companies do this, but you can't actually say this. You have to keep it to yourself and use it as part of a decision along with other factors. You certainly shouldn't advertise this.

Glassdoor gives them a 3.6/5 review. Highest category is work/life balance. 93% approve of the CEO. Most of the employees on here were approached by campus recruiters (39%) or general recruiters (20%). 62% report a positive interview experience. 24% were negative. They have an average benefits plan.

Indeed.com gives them a 4.1/5 rating. Again, highest category is work/life balance.

Xoriant was recognized as one of the "Best Companies to work for - 2019" by Silicon India. [May 2019 issue https://special.siliconindia.com/vendor/best-companies-to-wo... ]

The salaries they pay are in the average to slightly above average range.

Xoriant was actually founded in 1990, just after the 1987 HFT crash. They provide professional, secure, and cutting edge management and analysis of data for small to medium sized business worldwide. Their CEO Girish Gaitonde prides himself on his responsive agility, growing intelligence, efficient decision-making, and valuable experience.

They recently acquired CloudIO, expanded a new Global Delivery Center, and seems to be winning many awards. They are larger than their next 3 competitors [who all claim to be "one of Xoriant's rivals" ... using Xoriant by name and giving them free press as the leader in their sector] [There are actually 2 competitors who have a higher market cap, ASG and Blackberry, listed 9th and 10th. Nobody discusses them ... not my industry ... I have no idea why .. I don't think those two have a focused strategy to compete.]

This is more likely a strange fake job opening [I didn't see this position offered], a really bad recruiter, or a crazy person who had a bad experience with a senior data scientist and thinks that this ridiculous rant will attract professional talent who can fix their problems.

This email does not seem to represent the company, their values, other reviews online, current and former employee reviews, or any news items I could find. If the sender's email address was really from Xoriant, I'd bet the official recruiter [contacts are listed on the job postings] would love to hear from you about your experience with their recruiter. Attaching a copy of that email would help as an example reference for discussion...

In any event, it is an interesting post. If I were looking for a job, I would ignore it and block the sender of those emails from now on to keep this junk out of my head. It would steal focus from my main goal of finding a good group of people to work with. At the same time, I would look at the Xoriant website and apply directly. The company does sound interesting if this is your line of work.

just my 2 cp ...
