Having gone through this before with Broadcom and been part of one of the divisions that worked with the merger team here is what will happen.
Before merger, each functional area will prepare a “singing for your supper” presentation that outlines your orgs product, business model, profit margin, operating profit, headcount, etc. This will be used for Hock and team to determine just how incompetent your groups management team is and if you product line can be steered into Broadcom’s business model.
If your org can’t be a highly successful part of Broadcom, it will be sold to some su---r company. If your org can be merged into Broadcom, headcount targets will be set and your management will need to met that goal. Our org got an initial 25% layoff target. These meetings happen before the acquisition closes. To be part of Broadcom, you will need to be able #1 or a very close #2 in your respective area. If you aren’t, you are gone but most likely sold. Hock has an uncanny ability to find really stupid companies to sell complete cr-p divisions to. On day 1, you will likely find out if you are gone or not.
