Both PSU and IES have their own advantages. Here is some insight regarding both these services.
Postings:
In IES, each department except railways gives posting in metro cities or tier 2 cities. But in PSU, there are high chances that you will get a rural posting. Due to obvious reasons, most plants are set up in rural areas. DMRC, POSOCO are the only exceptions. So, if you want to live in metro cities, you should prefer IES. But most PSU has good townships set up near their plants. These townships have decent facilities like gyms, pools, clubs, shopping malls, etc.
Compensation/Salary:
PSUs offer better salary packages. Most PSUs offer a basic pay of INR 60,000. You will also get various allowances like cafeteria allowance, uniform allowance, etc. The CTC offered at most PSU is around INR 17-18 LPA, while it’s around INR 11-12 LPA in IES.
Authority:
In terms of authority, IES wins. No PSU job will offer you the power and authorities an IES service offers. IES jobs also have better respect in society.
Lifestyle/Facilities:
IES posts have more responsibilities. In sectors like railways, you need to be available 24*7. In terms of facilities, PSU is better. Large PSUs have almost every big private hospital in their panel.
You should choose one of these two services according to your preference.
Both are great government jobs and receives much respect and honor but it depends
on the individual's preference. Many people prefer IES but PSUs are also great
as their popularity is growing much rapidly. Having friends in both sectors I can share some of the important points -
Salary -
Position -
Facilities -
Career Progress -
Residence/Quarter -
Tours and Travel -
Job Security - As both of these are government jobs, so both of them are fully secure but in practical IES are a little more secure than PSU.
It ultimately depends on you, and what your preference is. IES is preferred by most but PSUs are also a good option.
