Usually if there is a high-profile case coming up, especially Federal, people who are in line for the pool are sent a questionnaire that asks some basic screening questions designed to weed out candidates that have an obvious conflict of interest.
This seems to not be the process in KS:
From the state's Federal webpage (underlying is mine)
Please be advised the U.S. District Court sends out
letters requesting juror qualification information to randomly selected registered voters in Kansas.
Collecting this information is the first step of a process undertaken every two years to develop a pool of qualified jurors who could be called for federal jury service. The
letter directs recipients to
www.ksd.uscourts.gov/eJUROR to answer a short series of questions and provides the phone number 800-959-9519 to call with any questions or concerns. The only personally identifiable information the court requests from you is a participant number, which is provided on the letter, and your date of birth. The court will not ask for your Social Security number, credit card or bank account information, or any other sensitive information. If you are uncomfortable providing information electronically through the secure website, or you do not have access to a computer, it is not necessary to contact the court. A
jury questionnaire form will automatically be mailed to those who do not respond via eJUROR. If you are still concerned about the legitimacy of any information being requested of you, please contact the jury department at
ejuror@ksd.uscourts.gov or 800-959-9519."
"Every month a number of jurors are selected from the qualified wheel and sent jury summons. The jury information form may be completed and returned by mail or completed on-line at
eJuror. The District of Kansas covers the entire state of Kansas so your summons will tell you which division you would report to, Kansas City, Topeka or Wichita."
"Pursuant to 28 U.S.C. 1861, all litigants “have the right to grand and petit jurors selected at random from a fair cross section of the community.” The court uses a two-step process to select jurors. First, a master jury wheel is created by selecting names at random from the official list of registered voters. Then, names are randomly drawn periodically from the master jury wheel to receive juror qualification questionnaires. Individuals’ answers to these questionnaires determine whether they are legally qualified to serve. If so, the names of those persons are put in a second or qualified wheel. As prospective jurors are needed for a specific trial or grand jury, jurors summonses are sent to persons randomly selected from the qualified wheel. All of these selections are carried out through a properly programmed electronic data processing system for pure randomized selection. The pure randomized process ensures that the mathematical odds of any single name being picked are substantially equal. Please see
D.Kan.Rule 38.1, Random Selection of Grand and Petit Jurors, for additional information."
At least according to the information above you don't get a questionnaire each Federal trial. You are sent a questionnaire but it's so you can be determined if you even fit into a pool of potential jurors. If your questionnaire passes (which seems they are just asking qualifying information like where you live, your criminal history, your citizenship information, etc) then you're added to the pool. From that pool you may be selected to be summoned for a jury duty. There is no indication that a questionnaire is sent
again after being summoned for jury duty or that the questions asked are to weed out conflicts of interests.
Further a link on the state's webpage goes to a U.S. Handbook for jurors in which case this is on the following "Questions are then asked to find out whether any individuals on the panel have any personal interest in the case or know of any reason why they cannot render an impartial verdict. The court also wants to know whether any member of the panel is related to or personally acquainted with the parties, their lawyers, or the witnesses who will appear during trial. Other questions will determine whether any panel members have a prejudice or a feeling that might influence them in rendering a verdict. Any juror having knowledge of the case should explain this to the judge." That is advised happens after a person is sworn in to be a potential juror.
Then again I'm just going off the information I have. I have not served on a Federal jury to give such information. I don't know what concessions are being done for covid in places that are not having in-person trials still.
