How long does a product company switch usually take end to end?
Budget three to four months from starting preparation to signing, plus your notice period on top. Preparation is the longest phase and the one candidates compress; the interview phase itself typically runs three to six weeks per company once loops begin. Across 14 verified switches the median was 11 weeks, and the median candidate finished with 4 offers in hand.
Should I resign before I have a written offer?
No. Verbal confirmations get withdrawn, budget freezes happen, and a resignation cannot usually be reversed without cost to your standing. Wait for the signed offer letter with a joining date on it, then resign. If your current employer needs longer notice than the new one wants, negotiate the joining date in writing rather than gambling on goodwill from either side.
What if I get one offer while other interviews are still running?
Tell the other companies immediately and ask them to compress their remaining rounds. Most will accelerate for a candidate with a live deadline, and a specific date is a legitimate reason rather than a pressure tactic. Then ask the first company for a reasonable decision window. Two weeks is normally granted, and a demand for a same-day answer is a signal worth noticing.
Is there a better or worse time of year to switch in India?
Hiring is uneven across the year, but the timing you control matters far more than the calendar does. Your appraisal cycle, your notice period and how prepared you are will set the outcome more than the month you apply in. Waiting for a supposedly better quarter while unprepared is a worse plan than being ready and applying into an average one.
