This timeline illustrates the typical flow from initial contact to final assessment. You should use this structure to plan your preparation, ensuring you have clear, concise stories prepared for your screening, and deeper technical scenarios ready for the manager-led interviews. Remember that the pace can vary depending on the clearance level required for the specific position.
