@sb I have worked with many colleagues from STCB over the years.
Indians are used to being employed as IT support for the likes of IBM. In these tech jobs they are paid to stay in front of a computer 24/7 and their rent, food, electricity, water, aircon, Netflix, Amazon Prime, Disney+, whatever you can think of, are paid for so that they can say "Hello, how may I help you?" when the notification pops up.
Such a person would refuse a Shell job. Too much, boring work for too little pay, when proper tech companies are out there. STCB staff are paid poorly compared to tech workers. SBO staff are paid 5x less than the regular STCB staff.
When someone from SBO costs 20x less than a western JG5, bosses are pretty happy to take the chance on the SBO guy. So instead of the JG5 solving something in 1 hour, the JG5 needs to book 2 hours to train the SBO guy, the SBO guy goes away for 1 week, delivers the wrong thing and the JG5 spends another 2 hours cleaning up the mess and gets told off for delaying the delivery.
