Apart from ESE, GATE, and PSUs many exams are held to recruit in various organizations in India, such as -
1- Railway recruitment board (SSE & JE )- RRB takes exams for junior engineers and senior section engineers. Although it is a group C job after 12 to 13 years of experience with time-to-time promotions you will be promoted to a group A job equivalent to an ESE/IES officer.
2- SSC-JE: it is a group B job and it is conducted for the recruitments in various posts in various departments such as Military Engineering Services (MS). you will be subordinate to an ESE/IES officer.
3- NPCIL: A subsidiary of Bhabha Atomic Research Center. Every year they conduct their own exams for recruitment usually in the month of June and July.
4- SAIL: It also conducts its own exam for recruitment.
5- Visakhapatnam - It is one of the units of Rashtriya Ispat Nigam Limited (RINL).
6- DMRC/LMRC/NMRC/BMRC: It conducts exams for different technical posts.
7- AFCAT: This test is conducted by the IAF for the selection of officers in various branches of the Indian Air Force.
8- Some other PSUs are BEL, BSNL, HAL, MTNL, SCIL, RBI, EII, BARC, ECI, etc. Other than these exams State Engineering Services exams are conducted from time to time by different states.

The difference between a GATE score and GATE marks:
1- The difference between GATE marks and GATE scores is that GATE marks are calculated on a scale of 100, whereas GATE scores are calculated on a scale of 1000. The GATE Score is calculated on the basis of normalized marks and taking actual marks.
2- The GATE Score is widely accepted by the Public Sector Undertaking bodies as well as the Indian Institutes of Technology, Indian Institute of Science, and National Indian Institutes of Technology at the time of admission into higher studies. Moreover, some foreign universities accept GATE scores as well.
3- The GATE marks are calculated on the basis of weightage on each ques and the number of ques. The total number of ques asked in the Graduate Aptitude Test in Engineering Written test is 65. There are 3 types of ques that are MCQs, Multiple Selected Questions, and NAT ques.
4- There is a total of 100 marks. The negative marks are only applicable to Multiple Choice Questions. One-third of the marks allocated to each MCQ will be deducted. GATE marks are the raw or actual marks that students received in the examination based on their performance.
