Estimate is around 8500 in count. (Max 12000 if more layoffs in India)
USA - 2,800 people to 3200
India - 4200 - 6500 (Expecting more cuts)
Europe - 1000 to 1500 max
More will be in Software dev and support : 5000+ counts expected (Middleware, DB, ...)
OCI will be saved with minimal layoffs <1000
Seems the 30000 layoff is not immediate and it will be over long term. Seems the estimate was done by the firm for long-term analysis and not for this year and the estimate was purely based on funding to the future commitments.
Basically Senior Management with mostly India team with non-revenue workloads beware . You will be major targets. !00% you can start searching new jobs.
