Verdict: Selected but didn’t accept the Offer.
Reason: I haven’t accepted the Verbal offer since this offer was not directly from Semtech Corporation; it was from a Third-party (which means there was a verbal discussion before sending an offer letter, during this time, I have mentioned I would not accept the offer in a Professional way). Also, I had one more offer during this time, so I haven’t accepted.
